Head Decoding, and Winters intake. HELP
I have a set of GM heads. The casting number is 3927186. Could be from 68-69 302 or 350. With 2.02, 1.60 valve's. how can i tell if there "double hump" heads? Also 302 i think was only z28 camaros. soo i think thos are reall rare. the intake is a casting 3972110, with the Winters snow flake. its from a 1970. Is it rare?
Thanks
Thanks

The "double humps" are cast into each end of the heads.

I guess I got somewhat of a rare find. When I was researching earlier. It only gave me 68-69 for the casting number on the heads. Well With more investigation the heads are 70 date coded. Thanks. and These are 2.02 in, 1.60 ex
