There are several engines in that yellowbullet link I posted (some of you guys?) running the Indy SR heads making north of 800hp on mild builds. I just thought the Edelbrock Heads should out perform them with the larger intake valve.

My build is a Musclemotors 604, CNC ported Indy SR, custom solid roller, and as of today Barton rocker arms. Hoping to be >800hp and able to survive Drag Weekend and Drag Week.
