heads for a 318

Dont use the 360 heads.They have large combustion chambers and will drop your compression in the 318 to as low as 7.5:1.Better off to use some ported 302 casting # heads. They have swirl ports and a small heart shaped chamber that will bring comp up to about 8.5:1 without milling.The ports are small but this will work better with the intake and cam you have.Put a 1.88 intake valve in the 302 head and do some bowl work.

Should make about 300 hp.
