As a standard member, you can only post one photo, so perhaps this is your issue with posting pictures.

Found this from a Corvette site when I googled your casting numbers:

Small Block Chevy Cylinder Head Indentification

1968-69 3927186 302 2.02 1.6
1968-69 3927186 327 2.02 1.6
1970-72 3927186 350 2.02 1.6
1969 3927188 307 1.72 1.5
1969 3927188 327 1.72 1.5
1969 3927188 350 1.72 1.5

SBC heads have or don't have bolt holes on the ends as well as a pattern cast into the ends that helps to ID them. Then there are the casting numbers that ID the heads. Why not search on the casting number?

I have done lots of research. The problem is that the casting numbers are somewhat difficult to read, 186 or 188? I don’t beleave the 188 heads from a 307 had 2.02’s or double humps. If I can figure out how to upgrade my membership I will post the pic’s. Thanks for the reply’s!
