Does anyone know a conclusive list of headers (long and shorty) that would be compatible with a 289, GT40P heads, and the 67-68 body style?
I have searched through the archives and havent really found anything conclusive. In addition I have went through several other websites and couldnt really find any specs. Some of the names that did come up were BBK and MAC but these were on late model stangs dont know if they would work.
Currently running 88300 Hedman longtube headers, from what I hear they cannot be modified even with a BFH. Anybody try using these before with the gt40ps?
