Re: help on cylinder head info...
i figured out this combo would work because the cylinder heads can support a .600" lift and the cam i'm looking at has a .550" lift....thanks for that answer Qwksnke that cleared up alot.....now i just have to worry about how much the shop is gonna charge to put this combo together....

If you do the cams, the comp 270's are prone to PTV. The comp 262's are the safest bet, but yield the least HP. MPH also offers VT cams, and head packages.

the heads may handle .600 lift but your OEM pistons won't
