Depends on the cam.

I am running a 590 lift ARE/Lunati cam, and Comp Cam 987-16 springs.

 

Agreed <img src="gr_grin.gif" border="0"> I'm running 987 Double Springs with my cam, it's a .591 lift.

 

987s with .561 lift, no valve float or any other problems.

 

What springs are the best?????

 

I'm going to be running a 226/234/114 .554/.575 cam and just want the best parts!!!!I know my cam isn't as big as you guy's.Only going to have this set-up for this summer.408 solid roller going in next winter!!!!!!

 

Many guys run a single spring with that cam.. I run a Crane Double Spring and the problem I ran into was diameter.. 1.46" seems to be too wide to use the stock rocker arms with at 1.8" install height. B4 I chose the spring I did a search on the diameter and I could not find anyone having a clearance issue.. So I had to find out for myself..
