Clearwater 0331 head valve spring issue
Posted: December 19th, 2023, 7:40 am
Hello All,
Hope to find a solution on here. Bought a head from Clearwater (new 0331 casting with the big valves and upgraded springs) and the machine shop Im using is telling me that the springs only have 35 thousands bind clearance with the cam Im using which is a comp 163-301-5. The machine shop is telling me I need different spring in order to gain at least a 60 thousands clearance. I called clearwater and they are telling me that those are the springs that they have been using for over ten years with no issues.
So, not having enough knowledge into this issue, who is wrong and who is right. Is 35 thousands clearance on stroker ok? or should I look for other springs?
If other spring is the better route, what springs to use? and if anyone on here has had this issue as well.
Any help would be appreciated.
Thank you
