The headers fit on my 906 heads fine, but with the angled plugs on the new heads they surely will not "bolt right up". The car is a 67' Barracuda and the engine compartment is tight. Has anyone modified a set of proparts headers to fit the edelbrock heads and have some insight on what to expect? Its looking like my #1 pipe will hit the #5 plug and the passengers side header looks like some "dinging might occur for plugs atleast. These headers are nice, finished by QC Coatings I hate modifing them with all the money tied up into them.

Or just yank the starter.

I'm probally going to have to end up with a custom built set of headers with either a 2 1/8 or 2 1/4 pipes for that motor Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

My concerns are that the headers are designed for original spark plug location, not the angled plugs on the Edelbrock heads. What headers does everybody run with Edelbrock aluminum heads on there 440's in an A-body? Surely im not the fist person who upgraded there stock 440 head with the Edelbrock units only to find out there proparts headers dont fit.

The relationship between the headers and the plugs is the same on eithier motor. If the headers clear the angled plug configuration on a 383 they will also do the same on a 440, am I correct in thinking this. Having said that, does anybody have any pics of a set of ProParts headers mounted up to the Performer Heads?
