ok so like the title says I have a b18c1 head with Stock Springs And Retainers. My Question Is Can I Run crower Stage 3 Camshafts With Stock Springs And Retainers? Only Planning On Reving Up to 8k RPM And Not verry often. My Build Is A B16A Block With 12:5:1 Pistons, Eagle H-Beam Rods, And Eagle Chromoly Crankshaft. Any Answers Would Be Great. Thanks!
