2.7t titanium valves or opening lifter bucket bores

[Kfsii]

Does anyone know of any off the shelf titanium valves for the2.7t or 1.8t 5v per cylinder we have every small space for valve springs and hopefully I can source some. Has anyone opened up the lifter bucket bores to accommodate bigger springs?

What would be the goal of all this? Not trying to be snide, just genuinely curious… 2.7/2.8 heads can be easily modified with off the shelf valves and it’s not a common failure point on builds. Money better spent elsewhere than on Ti valves IMO unless you have a very specific application?

I remember some builds years back where people were taking the stock valve train to 7500rpm.

I also think on 12v.org, the lightweight valvetrain had stronger springs (obviously) but the only other difference was the lifter bucket being about 30-40% lighter than stock, which allowed you to rev it up over 7500

No off the shelf Ti available. Would have to be custom made. For a race engine you can save quite a bit of valve train weight by going with solid lifters
