Ran a set on one RB, no problems. Did need some cleanup & porting to get good flow #s (Edelbrock's were exaggerated), and I swapped to a double spring.
Stealths on another, stronger RB; I like the OEM appearance, again worked fine, same mods.
Folks seem to really like the TrickFlow 240s & 270s, reporting more power.

For anything that doesn't have to be restored/stock, I prefer aluminum heads by a mile:
Lighter weight
Better flow usually than OEM
Easier to port, or repair if need be
Less detonation sensitive
More CR options depending on application
