What kind of heads do you put on a GT40?

I put on GT-40 heads milled .030. 1.7 roller rockers, Explorer intake, Explorer 65 mm Throttle body and a 75mm mass air meter with 24 lb. injectors. Bone stock short block and camshaft. 1 5/8″ shorty headers and a complete Flowmaster 2 1/2″ exhaust with a off road H-pipe and 3.73 gears.

Which is better GT40P or B cam heads?

The GT40p heads have the larger intake valve plus smaller 58cc combustion chambers which helps low end torque…and coupled with the larger ports will also breath on the big end. The B cam will be about the same as installing the 1.7 rockers on the stock cam.

Which is better a GT40 or an E7 head?

I’ve got GT40 heads on my ’85 and love ’em. GT40p heads are usually worth about 30hp more than a stock E7 head. A good aluminum head (AFR 165 or TFS TW 170) is worth close to 90hp more than a E7 head on a similarly prepaired 5.0 engine.

Which is better the B303 or the stock Cam?

The B303 and stock cam are not close. At all. Not even a lil’ bit. Like not even remotely close. Personally I really like the B303 for the right setup and usage, but it needs 1.7 rockers. I also have much respect for the stock cam. It can do great things in the right setup and it too benefits from 1.7 rockers.
