what is stock rocker size? and why on like thunder racing's site does it say rockers of sizes over 1.7 are not recommened? What would happen if you put bigger rockers on, i mean i understand that the cam has a higher ramp rate.. but what would happen?

You know, I could just get the turbo and keep it at low boost (whatever gets me into the low 13s), but I'm afraid the tranny will let go eventually.

1.7 is stock size..i guess they say that for valve to piston clearance issues.

bascially you'd be at .606 lift. it's not impossible. the sprigns have to be able to handle that lift. then you would need to check the piston to valve clearance.
