Edelbrocks and stealths are all standard port and valve geometry. I run the steaths for 2 years and couple thousand miles with no issues. They flow well and are cheap. I am no tuner and I got my 4000+lb brick to go 11.67 first time out on 8 psi boost.

11.67@118 1.88 60' with only 7-8 lbs of boost. Turbocharged, megasquirted, 407 BB, 440 source heads, roller cam, 9:1 comp. http://s292.photobucket.com/albums/mm14/beansgracie
