His current valve springs may not be the specific issue at hand in his situation but once he gets it all sorted out those cheap Edelbrock single coil springs set up 0.250" away from coil bind is NOT optimum ! That was the point. That said, with the tiny cam it will peak out at such a low rpm anyway so no big deal.
