Has anyone ever checked this clearance on their VG? I'm building a new VG33E and I have a couple potential issues. One, the machine shop I used milled the heads .010" and after I decided to do some block work after all, I may end up decking it .003" to take care of the slight twist. This combined .013" is more than the .008" combined spec offered in the FSM. I can't find a thicker head gasket and I'm planning to use early Z31 cams with a little more lift (0.039" more). I want to make sure I'm not going to have a clearance issue.
I'm not 100% certain what the impact is of the suggested .008" combined block deck and head milling is, but I calculated combustion chamber volume difference from milling the heads and the impact on mechanical valve timing from the combined physical difference in elevation between the camshaft and the crankshaft and both are negligible. I'm guessing the risk of going past the .008" would be piston to valve clearance.
Anyone ever measured these or know if I'll run into any trouble with this setup?
Thanks!!
