Coil spring front, OBX headers. I had to trim the engine mount plate to get them to fit, but have had no problems other than clearancing a pipe or two so I could get a socket onto the bolt.

Anyways, I know these were specifically built for the GT40P head, and everything that I've read about the aluminum heads they are based on the GT40 head.

Does anybody know if these headers will work on aluminum heads, or any specific type of head?

That's not so bad. My main concern was the bolt pattern being different, exhaust ports not lining up, or spark plug interference.

Those trick flow heads a major upgrade? I have heard good things from others.

Nothing crazy. Cam/roller rockers/MSD coils/SCT x3 tune. Didn't want anything so radical that I needed to run higher octane fuel. Mostly a street vehicle.

All emissions stuff is still intact, if my county goes to emissions checks, no way will I pass without it all :(
Probably wouldn't pass anyways. Government sucks
