(Edited) This is a ....."factual"..... discussion! If there was "extensive research" done, some of it should be available for you to post online to back up what you say about the 305 and other stuff.!

Westlake heads were used for Chrysler's Indy effort and by the Rod Shop in one of their Gas class Colts. Not legal for Nascar or Trans Am racing.

Nascar 305 w/production type heads.

Much more info is available online on the 305 applications.

I don't mind learning something new or getting errors corrected, IF the information is accurate. Not trying to get political, but here is too much of history being erased or changed as it is. Please confirm your info.
