Exhaust ports/ headers.
 
Besides for size, are all the exhaust ports in the same configuration as the 305's.I am almost done with a set of headers and am wondering if they would fit all the V-6's. Also, how about 4 wheel drives and stick vehicles, for obstruction. With in the next several weeks I should have them ready to have it sourced out some low quantity build. I am not sure if there is any interest in them or does everyone want factory items. Any help you guys can give me would be greatly appreciated, John.

HOTRODJOHN,

Will you be making sets for the magnum heads?

Are the ones you are building now like shorty headers?

Any pics yet?

As I understand it there are basically two different type of heads. The 305 version and the magnum version. I sure someone in the group can offer more info. Magnum version has larger intake and exhaust ports.

So far I am doing a set for a 305 and I guess I am going to get a set of Magnum exhaust gaskets, to see the major difference. I have 2 305's myself so I will be doing them first and when I am close to being done I will post photos. They will be long headers. Thanks for the feed back. John
