Has anyone used these heads or seen them in person. The reason i ask is i'm thinking about buying a set for my car and would like some input on them. I know there cnc'd and assembled at MCH but how are the parts they use like valves,springs and retainers quality wise?
Thanks for all and any info

I would like to hear the reviews of this also!

 

I had a pair of the Stealth Heads before I stepped up to the RPM Performers..They are a good bang for the buck...however the springs...retainers and locks are poor. Get the better locks and retainers and remember that their valves are 11/32". People have put the wrong size locks and retainers on before with terrible results. Match your springs to your cam. Do not try to go cheap on the springs...retainers and locks.
