Max Compression Ratio in STU....

[JS154]

Thanks Greg,

I'll get the thicker head gasket. That's crazy because, E-production has the exact same compression ratio and cam limits, the only differences are h-beam rods and dry sump oil system.

STU allows replacement rods, pistons and dry sump systems.

you could also shave down your piston tops if it is a domed/pyramid type.

Thanks Eric, I figure that a +0.030 thicker MLS gasket ought to lower the compression by 1/2 a point. At this point I don't want to mill the dome as I'd then have to have the top ceramic treatment redone.
