Re: Head flange adapror?

I've built a lot of engines and I've never heard of a "head flange". Did you mean header flange?

Re: Head flange adaptor?

Actually it is an adaptor so that earlier model heads can be run with late model exhaust manifolds. It modifies the 7th hole so that it is spaced to fit the manifolds like the 305's with the wide spacing on the rear passenger side bolts. Some call it a 7th hole head adaptor.
