I'm putting a new set of springs on my cousins GT 40 steel heads. Comp. cam springs with new keepers and retainers. I didn't talk to Comp. but they told him the installed height needs to be 1.800. What are the tolerances, plus or minus how many thousands? Say 1.790- 1.810 spring height Icon_scratch Thanks guys

The 1.790" to 1.810" range will work fine. If it's .015" or more, then you need to start adding hardened shims under the spring cups.

Hope this helps,
