[ERA Chas]

No apology needed or offense taken. My post was not intended as a "defense" of Shels. Absolutely E'Brocks, as improved by KCR, George, Mike and several others are killer and best bang for buck. I just wanted to state clearly that the improvement was substantial for my combination at 427 inches, even above my previously modified iron MR's.
BT's heads also are super with a very small amount of work. I watched Barry Rabotnick make 751 HP with his 509" FE. (Note the gains are larger with larger displacements.) In fact Barry should chime in here since he's now in the FE business with his new company "Survivor Motorsports".
Forgot to mention that my Shels were Stage III in earlier post. On a subjective level, the castings were beautiful and flawless with quality valves, springs, keepers and Ti retainers.
I'm a sucker for that kind of stuff too, but not his signature. The BT's too, are well done but I've heard some E'Brocks need TLC.
