Saw the post on ClubGP...should mention he has a class that allows hom use of the machine shop.
Overbore=bad idea...block gets too thin there.
I'd get a set of L36 pstons and rods, just so you can say you touched the block and bump compression
Don't deck the heads, just a light skim to make sure they're straight. Our valvetrain is non-adjustible, if you deck the head or go with a thinner headgasket as suggested, you'll need custom length pushrods
XP+3.0 and 9.5 compression=probably won't fly w/o an IC. You will need to acess a custom tune and roll back the timing.
If they still have the VSX cam, it would probably do you better non-ic'd to be honest. The extra exhaust duration will help you out.
If you can get the set-up you're looking to do to work with no KR, you can be 12.6-8 easy.
Don't fret on the 3.0" pulley. The higher comp ratio is the equivalent to adding more boost. On that set-up, a 3.25 would work fine for 12's, plus you won't be developing as much heat with the SC.
