Valve Spring Q's

junior73 · 06-20-2006, 04:36 PM

A friend of mine had a set of 351W heads built while he was in California. the problem is, he lost the info on the springs.
They are double springs, with the inner spring having a blue stripe, and the outer with orange on one side and yellow on the other.
the size is 1-13/16 diameter, and 2-7/8" high.

Any help is greatly appriciated.

All I can recommend is taking them to a machine shop and letting them check for bind.

This is really the only way to know how much cam you can run with that spring. Anything else is likely a guess.

Maybe a manufacturer painted the springs, or maybe the last shop to work on the springs painted them?
