    Hey guys, I'm trying to figure out what kind of heads are on my 5.0 The only thing I've got to go on is the engraved number "KX07A0202". The heads don't have anything else engraved or stamped. I have tried calling jegs, summit, edelbrock, trickflow and pro comp and none of them could tell me...

    I'm building a 302 to go in my 1965 mustang and I want to put a set of gt40 heads on it. I read that the gt40s have some issues with long tubes which is something else I'd like to have.

    I just picked up some used heads for a good price and I'm probably gonna have them ported and polished locally so I'm not looking to send them out. I was looking to use some of the same size specifications for the valves and ports as some of the high performance heads that are out there. I have...

    Hi, I was thinking today that this list that I made of bolt-ons I want to put in my car adds up to the cost of the cylinder heads at supersixmotorsports.com, and i think the horsepower gains of the cylinder heads probably out-weighs the hp gains from the bolt-ons. What I was wondering was: if i...
