I have a new motor being assembled with Edelbrock heads, its a big block and have some questions about what to expect with the spark plug interference. 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.
