Customer q:

I am looking for stock upgrade valve springs to support nitrous (100shot). The heads (E7) and cams are stock, but I will run 1.7rr on my exhaust. I have 125k on my springs and would like to replace them. Any suggestions? Thanks

JEGS ANSWER:

It is suggested to use a larger spring, this said with the 1.7 rockers use COMP cam springs #986-16, spring retainers 740-16 and valve locks 611-16

COMP Cams 986-16
‍Dual Valve Springs I.D.of Outer Dia: 1.070"

‍10° Super Lock Steel Retainers Valve Spring Diameter: 1.437" to 1.500"
