Does anyone make an oval port header (Ram Air IV) style to match the Edelbrock Oval port cylinder heads and install in a '73-'77 Lemans? I've been looking, but have had no luck. Not even Doug's headers makes one.
Hooker nd Dougs are the two that I know of.. If you have AC, hookers will be hard to fit without mods. Don't know about Doug's..
i have a set of real nice looking headman huslers round ports that were bought for a 79 trans am. i test fited them on my d ports to see if they would fit my 69 grand prix. they cleared no problem but i don't know if they would fit your lemans. the gp motor is set back and down lower than most pontiacs. lots of room behind the motor mounts!
