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
My first choice was unported Steaths. Out of stock. Trick Flows are a little bit out of the budget right now, but I have them on my 512 in my Super Bee and like them a lot. I looked into Promaxx(out of stock) and Sidewinder(also seem to be out of stock). Maybe by the time I get the crank and the block bored, some will be in stock, but I'm kind of inclined to buy some things before they are not available, either. I've heard of quality slipping on the E-brocks, and the fact that they are the only thing still to be found is rather concerning. But I'll just have them checked over before they get bolted on.
