thanks jack, i'll look into that, and mark could you post a pic of what the smog humps are, like i said im not much on the mechanicing side and dont know what those are, haha
The cheapest way to get heads I have found less somebody giving you a set is Pull A Part. As said finding a set of D3 heads but the heads you really want (factory cast) are C8, C9 or D0. I picked up a pair of C9's out of Pull A Part for $34 each. Depending on what you want to do they will serve you just fine. There are proven builds for 650hp+ with the cast heads. If you want good info on building the beast here are a couple links to check out.
do you have a ford dealership that sales ford motorsports they should have the heads you want and they will show you what you need to grind out of the exhaust ports so the engine can breath freely
sorry bout the shipping thing i was referring to the guy talking about pull a part, but thanks ill have to check on that, but won't they be a bit pricey?
