WCCH Stage 2 Heads Maintenance
I have the Stage 2 heads with the Manley 221435 Dual spring kit. Factory intake valve with ss exhaust valves. I'm not looking to debate the ss exhaust valves/dual valve spring valve train stability issues. Just wondering how long should I expect the valve springs to last. I've got about 10,000 miles on them with 10 or so track days. My cam specs are pretty close to the Katech k501 cam specs. Is it time to replace the springs? Thanks!

Really should be pulling a spring or to to put on a tester to see where they are at. They are more than likely still fine but you really should not be guessing or going off how long other forum members ran their springs. when in question always measure. Have your guy pull a few off and test them (open and closed).
