edelbrock cylinder heads

The engine in this photo is my 416 which pumped out 520 h.p. and 500 lbs. of tq. with BARELY touched Edelbrocks,can't wait to see how they perform when some serious port work is done to them..i'm not saying the rhs are no good,they're just no good for me i've had get results with the Edelbrocks and no reason to switch or try any other heads right now..
