Im planning on going to the junk yard to find some gt40pheads and intake. first of all what parts do i need for the swap? i know i need the heads, upper and lower intake, bolts, TB, EGR as well correct?, do I pick up gaskets for gt40p heads? what other little parts will i need to do to make the swap work? this is all im plannin on doing for now. I got a set of cheap summit long tubes that i have on now. will they work with the new heads? I plan on just doing the heads, intake. 3 cut angle on valves, i also want to port the heads, new cam.( what would be the best cam for this setup)? Should I get new springs and rockers? or any other little parts for the heads? I also want to shave the heads for more compression. how much can i shave them down on the stock motor? What size MAF will I need along with injectors? I know ill have to get the computer redone correct? and last how much can i advance the timing on this setup? Id appreciate the input. thanks alot! Does anybody have the heads, intake, and TB theyd like to sell BTW? I live in Florida so u can give me a rough cost for shipping. Its a 93 5.0 conv BTW.
