'60 aluminum heads questions

[George W.]

Hi all,
I've read that the casting number for the '60 aluminum heads is 3772894, and that these heads have two pipe plug fittings on the exhaust side of each head.
I have located a set of 3772895 aluminum heads dated 6 4 59 that do not have the pipe plugs.
What are these? Early prototypes for the Vette, other GM product?
Thanks,
george

Re: '60 aluminum heads questions

Those (3772895) are the 60 aluminum heads that were cast at GIF or Grey Iron Foundry and intended for use in the production cars. I belive the other with the pipe plugs were the first cast in Italy and prototypes. I have a set of the ones you have located and they have no pipe plugs cast in. Do yours look like the the pic of mine? GL
