Valve Spring Recommendation

they shouldn't (famous last words). per their specs they're set up for hydro cams up to that lift, so i'd assume you're in the clear. and they're single spring.

color me jealous, that's one of my favorite cams for 318's

ETA: the 60779 has single springs and is for flat tappet. 60775 is for roller cam and equipped with dual springs. just fyi
