SB Pro Comp Aluminum Heads...For Sale on Ebay..

It's funny how stock valves hold up under .600 lift and 150 seat psi's....and yet somehow a stainless valve wont, thats hilarious.

Engine pro, 120-140 a set of 16, Ive run them numerous builds without an issue.

I dont think the average guy running around with a .550-.575 lift cam and 10.1 needs 220 dollar a set valves or 365 dollar springs.

Im all about doing it right, but were not all running nascar or setting world records.
Its like the cheap rocker vs expensive rocker deal, i know plenty of guys including myself who've had no issues with the lower cost rockers....you have to know what ur doing and do the proper setting up. Im not talking about cutting corners, jsut saying overkill for the sake of making urself believe u have the best or that nothing can go wrong 'when it still can' is not the way to think.
