Engine and head numbers

[automart]

I pulled this 302 out of a Mach I we purchased, just wondering if these are the right engine and head numbers, if so, what year?
I do know it is a 302 GT motor as it has the roller cam.

Thanks

Engine E7TE

Head: 8F28

E7TE's with a date code of 8F28 would be June 28, 1988.
