those are hydraulic flat tappet springs. not roller.. they would work but i think it might float at higher rpm

This single valve spring is use on LT1 Production Corvettes. Small Image Technical Notes: Single spring with 1.30" O.D. and 1.26" solid height. The pressure at installed height is 85# @ 1.78" with 373# the average rate of pounds per inch. Use with retainer P/N 1016842

those are only 320 and 360 at full lift and lt1 springs suck for revving so do the math

 

Just pick up some LT4 springs for 35-40 bucks and call it a day.

 

Thanks guys. where can i buy LT4 springs?

Can i use the factory retainers?
