They are either 66-68 390 hipo heads with 67-70cc chambers or 67 352/390/410/428 heads with 71-74cc chambers. Both would have std 2.02 int and 1.55 ex valves. The C7AE-A is listed for both heads. What engine are you looking at? G.

ok here it is ,,, i got them off and they are C7AE-A with 14 bolt exhaust, standard valves,1.93x1.34 intake 1.84x1.28 exh. and 4.05 bore,, so i take these are 390GT heads
but now i have another set to get that are C6AE-R with 16 bolt exhaust but i havent took them off yet to determine the sizes of vavles and ports. Both sets are double spring and have the taller drip rails.

Sorry for your loss of friend Mike McGee, Shine. Great trans men are few and far between, it seems. Sadly, Mike Frade was only 66 and had been talking about retirement for ten years that I know...
