what do you have to say about this?

How thick is that head gasket if it drops static compression by 0.7:1? I've heard a couple horror stories about head gaskets that drop compression on boosted engines.

The thicker head gasket will not cause an issue with detonation. It reduces detonation on 91 octane, although some power is lost on racegas.

how thick is it?

stock is 1.22 mm thick and the 2.0 build gasket most use is from the ALT which is a naturally aspirated 2.0 20v over in europe and that is .9mm thick...

I'm not sure if that was supposed to answer my question or 317's.
Either way I'm not worried about detonation, there's other factors involved than the head gasket when we get on that topic.

What I am more curious about is the type of head gasket that's included in the kit. I've read up on the "sandwich" style head gaskets used for dropping compression, and so far I don't like the results. I'm not talking about a graphite, or a multilayer steel gasket, I just want to make sure it's not the (for the lack of better words) "Spacer" type.

This will be hard to keep up with if it is in three separate threads. I'm closing this one so we can focus on the thread in the main B5 A4 forum.

This link takes you to that thread. (http://audizine.com/forum/showthread.php?t=195454)
