Do I really need to swap out my valve springs on a .433 lift 500-4200 rpm is a good number but seeing as how its NOT .500 lift or higher I don't think the valve springs are needed until I max out the cam. When its time to should have valve seats hardened?

Asked by: Living legend
It's always recommended to run the valve springs called out for on the cam card . Hardened valve seats on any engine running today's pump gas.
