Need help identifying heads

[ACSPONY]

Stud mount with emissions provisions, I can't see any markings on the front. I'll need a rebuild eventually and I'm trying to decipher the top end to know what I should be pairing with it on the bottom. The only markings I've found are what looks like a "CP" and a "T"?

Where else should I be checking for markings without pulling the heads?
Thanks.

They look like E7's with a stud retrofit on them. Seems there are still pedestal channels under the rockers, so it's safe to assume. Thats what I think. GT Heads all have certain bars, and e7 should be located somewhere in there.... or even e6... depending on the year.

Look at the four corners outside the valve covers.

Look like e7 heads to me

Based on this picture I found of E7TE heads, I think I have my answer. I guess they were pulled and machined for the studs at some point.

Thanks for the replies guys.
