I'm am going to replace my vavlesprings soon. I did some searching, and it looks like I want springs with about 80-85 lb pressure. What springs does Poston's sell? Are they the Comp Cams 980's? I'm also going to get the valve seals too. And i'm gonna get the tool from Kirbans. TIA.
 
jegs or summit
Comp cams 979 springs
They are plenty

Noticed a difference in my GN after replacing them with slightly over a hundred K on the clock.

I had a hook up at a speed shop spring test the OEM springs and 2-3 fell out of range and the rest were at min spec.

These were referred to me by Red Armstrong (quad air).
