I believe Ottmundr is referring to changing the springs to match the required specifications for the camshaft (open/closed loads, spring rate, coil bind clearance, etc.) if you have not already done so.
1 step forward, 2 back. I bought those SM heads complete so I didn't have to mess around with the springs. Wish I would have thought about it when ordering the cam. Wonder if SM has specs for the heads I have...
