Valve spring ?

I wouldn't run those Springs with even .500 lift., let alone .600.lol
They always recommended way too light of spring pressure for their cams

Lol, they claimed the DC/MP grinds were smoother....thus revving higher & requiring less spring, We were running the blue stripe double "068"'s on the 292°/.508" six barrel engine....I'd say they were just enough.
