Will someone please verify these used parts for me?

[N8Miller]

hi guys. my cousin just bought some very quality used parts off stangnet classifieds, but, just for his peice of mind, he would like someone to verify these heads and roller rockers.
the rockers have the # f3ze-6529-ab stamped on them and the heads are GT40s----not Ps---how i can tell what they are? i see F1zeAA stamped on the underside of the heads and on the top is has "3E3" and "GT" stamped on them.
again, this isnt to think we got ripped off, becasue Quarterpounder was very good about this sale.... but its for my cousins peace of mind.
thanks

Those are the correct casting numbers for the regular gt40's, I'm not sure about the roller rockers.

The cast in "GT" logo is a dead giveaway for the heads, sorry can't help with the rockers though.

Rockers are the 93 Cobra 1.7's (Crane), F3 = 93, Z = Cobra, another thing to check for on the GT40 heads is the 3 vertical bars on the ends
