I have a chance to buy another set of Alum heads(used) in great cond for $500.00.
The problem is the seller does not know who made them. They look like great heads 2.02/1.60's Assy bolt holes, 7 bolt exhaust flange.

The markings dont look my RHS and they anit Patriots.
So I have called
Dart.
Edelbrock.
Afr.
Procomp.(no tech line to call. waiting on email return)

Heres the #'s lazer etched on the intake side just between the valve cover and the intake bolts. HQ 030-111-195-0612-0339
HQ 030-111-195-0612-0344
Also they have a hand stamped # on the unfinshed part on the end of the head. 61207 U

Any ideas?
