I recomend only using the SS Roller Rockers on Solid Roller Cams. John Ageles runs PRW's. He did THE EXACT same thing with his Aluminums. Changed to the PRW SS Rockers and is still running them today. But John is running SICK valve spring pressure. Up in the 450 lbs area CLOSED!!

I only Recomend the PRW Stainless Steel Rockers on Solid Roller Cams. The spring pressure of a Solid Roller is just to much for the Aluminums. But of course this is only my experience and opinion.
