Bb Chevy Heads?
Help, I need to find someone that can tell me the intake and exhaust valve sizes that are installed in the following heads.
casting # 3931063 closed chamber date code D11-9
casting # 3964290 closed chamber date code H20-9
The heads are virgin rebuildable as removed oval port. Are there any differences between these heads except for cast #'s and dates?????
Ditto on the model kits! My best were lost when the Hobby Shop burned under suspicious circumstances....
