Problems occured:
Waiting for parts (make sure you have it all before you start!)
Idle issue, caused by leaky intake, and loose bolts on the TB
Head demolitoin: I learned the hard way that you NEED to use loctite on that crank bolt or else it WILL losen and destroy about 16 valves or so.
Misfire: caused by slightly bent intake valve that would seal itself up fine, and bad valve seals.


Im going to unify my threads into one nice build up in this thread when i get more time...

[t1demont1]

The beginning

Day of pulling the motor


Getting to work






After a long day of work

[t1demont1]

The tear down


Accesories off, head off


The cause of a lot of drive train slack


dirtay pistons

[t1demont1]

During downtime, I found some time to become creative


showing off the 3" TB and the difference between a 3071r and a k03

[Wizard-of-OD]

Man come on...post up more pictures!

[t1demont1]

She found some new shoes in her downtime

[t1demont1]

pistons back in with SCAT rods, 034 main bearings, and 034 rod bearings. Accesories also ging back on


Head back on, and more accesories

[t1demont1]

Tranny back on with Southbend stg5 clutch, fidanza 9lb flywheel, and 20/80 center diff mod.

[t1demont1]

Finding her home








All in, just need to do incercooler piping

[Don Supreme]

How do you feel about that 9lb flywheel?

[t1demont1]

How she sits now




034 fp guage

[t1demont1]

After she was running for a couple weeks, the bolt on my cam gear sprocket losened and my origonal head went bye bye, bending about 16valves. So i purchased a head which was form a car that was "running" when it was pulled. One week after purchase the head arrives to have this problem




Got the the exhaust valves upgraded to supertechs by a euro tuning shop down here only for them to fail. I brought them the vavle guides which they didnt install. I put the head on, car started but barley fires cyl 2. After compression and leakdown tests with nothing showing i pulled the head. I noticed oil in the exhaust port of cyl2 form a bad seal. Dropped the head off at a repudable machine shop monday. Today, wed. they get back to me saying the valve guides are warn and an intake valve is slightly warn. So now the head is getting that valve replaced, all the seals replaced, and the exhaust vavle guides replaced. Should be done monday, well see :D

Thats all for now folks

[t1demont1]

ma head is hurr :D, shop found another fucked up intake valve from a incorrectly installed seal or something. so they replaced that valve with out uppin the price. Shes all clean and decked. im gonna go install her :D :D :D

so i had:
intake valves replaced: x2
all seals replaced
all exhaust guides replaced
decked
cleaned

plus the supertech exhaust valves chillin in there from the first work i had done on the motor means this baby is ready to purr

[Poopie]

cost on that head work?

[pipe7284]

HURRY UP!!!!!!!

[1fstavant]

nice build love seein all these bad boy builds...starting my thread again in a day or so

[t1demont1]

cost on that head work?

500 bucks :(

[pipe7284]

damn, that much. i got mine done for $200

[Don Supreme]

damn, that much. i got mine done for $200

What work was done to your head exactly?

$500 sounds about right for a proper job.

[1fstavant]

mines costing 500...shop fuckd up tho and quoted me 1400 to do my work...eating 300 yay

[t1demont1]

Yeah i feel 500 is about the average price. They pulled everything and checked everything. replaced all the seals, exhaust valve guides, replaced 2 intake valves that were messed up, decked the head, cleaned it up, and leak tested. Ive seen people pay more for less. i think they did something to the intake valves too but i forget what. even though we have 5valves im glad we only have one head lol. Id cry if i messed up a 03-04 cobra top end. 2 heads 4valves

[Don Supreme]

Did you get a 3 angle valve job?

[t1demont1]

no, did not... didnt even think of it. probably should have, but o well

[A4 TSCHUSS]

Cost me $350 to have the valve seats cut and new valve seals put in along with reinstalling the valves and springs (new springs and exhaust valves I supplied). $300 for the labor and $50 for the seals (got shafted on the seals since they are like $1/piece from ECS Tuning)

What about valve guides and a valve job?

Sounds about right. Glad to hear its done correctly and all the necessary checks and balances were covered.

Imagine having to do two of these heads? That's what the B5 S4 guys are doing.



David. I hope you got valve guides installed or at least had them measured for wear.

[Don Supreme]

Sean, how familiar does this look?

I thought of you when I saw that picture.

[t1demont1]

what fuckin good is anybody anymore? This damn head still isnt fuckin fixed! wtf?! before i threw the head on, I put the head on its side and spun the cams to check everything out. I noticed on cyl2, the cyl I had problems with, an intake valve looked like it wasnt shut all the way when it was supposed to be. So i took a flashlight and shined it into the intake ports sure enough all was dark when closed except for this one fucking valve on cyl 2. Im so pissed, so im going to the machine shop tomorrow after school. wooo fckin hooo more downtime because this head was failed to be fixed twice now. Im guessing its a valve seat, but why the hell wouldnt they check that

[t1demont1]

now i feel fuckin crazy because i went back out into the garage to look at it again and its not doing it anymore?! wtf would cause this? I dont wanna put the head on the car becasue i know somethings not right, but im gonna have a hard time explaining this phenomenon to anyone. i wish i snapped a pick of the light getting through.

[t1demont1]

How am supposed to explain this to a machine shop and tell them to fix something that doesnt look wrong but i know is.

[Don Supreme]

Did they pressure test the head?

[t1demont1]

Ill ask them when i call them tomorrow morning I dont think they did, i think all they did was pour oil into the intake and exhaust ports to see if they leaked out the valves at all since there was some fresh oil on the head when i picked it up. Im not sure if pressure testing would show anything since this didnt even show up on my compression tests and leak down.

I just know what i saw was what caused my cyl2 not to fire when the head was on. I have a feeling if i saw it open then, it wont seat properly when the cars running and the cams are opening and closing thousands of times a minute

[Poopie]

I don't think its the seat. Double check the lifter and the springs.

[t1demont1]

I thought it might be the seat because it looked seated on one half, but the other half was open. Im 99% sure its not the lifter becasue the cam never even hit the lifter once when i noticed the valve was open

[Poopie]

did that valve get replaced? hhmmm sounds like a crooked guide maybe.

[pipe7284]

wow Brended, this sucks. that head has cost you alot more than the BT build...lol

[Poopie]

my head will end up being the most expensive part of my build. when all said and done i've probably sunk about 2gs in my head and its not even ported.

used aeb head with a ton of bent valves - $150
clean and 3 angle valve - $200
replaced a few lifters - $70
revolver cams - $600
new valves - $500
cam chain tensioner - $140
034 valve springs $250

uugghhh so sad and i still need to buy new guides and have them installed...which will be like $250

Tell me about it man...

Used AEB head - $150
Supertech Exhaust Valves
Cat Gold Valvesprings
Ti Retainers
Cat 3652 Cams
Cat cam gear

probably ~$2100

[t1demont1]

yeah taht valve was replaced. all the vavles were put on a machine and tested for straightness. I was told all the intake guides were good and that exhaust guides wear out way before intake guides. maybe its the spring... it looks like it gets really close to the head, so maybe it could grab the head on compression and not release right away? defect in the head or something?


i want this shit figured out god damn i just wanna drive this beast. at this time i wish i would have spent the extra cash and gotten vavle springs and titanium retainers and had them put in so i could throw in cams later.
