Would new stiffer springs be required?

New 980's (Z-28 springs) definitely.........there are a few different opinions about spring pressure and rollers. The 258HR is not an aggressive grind at all compared to what's out there....it's a great street grind......so 980's should be good to around 5200 R.P.M. according to my Chevy builder friends.........and they should know. Pressure across the nose is most important.........and 980's are around 325lbs. I believe, which is sufficient.

Cam and button alone are worth $300...............make me an offer. Can be used with Comp Cams roller lifters and pushrods as well.
