small block Mopar W-2 heads, intakes, and rocker arm set.

One picture has “ARROW” stamped on it. Which set is that and which is the ones you think are “DIAMOND” heads?

Nice parts by the way.
WOW!
The complete unported heads are the ones stamped Arrow racing. The bare ported heads that are stamped DRE are from what I can research the Diamond racing? Butch Elkins ported heads. Thank you, Matt
