308 valvesprings

bellbigdawg

looking for some better or stronger valvesprings for my 7x build, heard early 60's corvette 6 cyl. valvesprings fit perfect. more seat and open pressure by 20 lbs. anyone know if this works, or any old isky valvesprings out there??

fyi

Ive used Chevy Sealed Power VS 677 that have more Open & Closed pressure in a couple of motors, (not to say there may be other Sprg's that will work. too)...I ck installed Hgts and for coil bind but have had no problem. I use Chevy retainers on the Int and Hudson on the Exh, because of their shorter Stem Lengths....
