My motor is a JDM D series, got a crower stage 3 cam and a full set of supertech valve springs for it. Wondering if I could get by using the stiffer (supertech) springs just only for the intake side and use stock intake (stiffer than stock exhaust) springs for exhaust. The reason for this is to reduce valve train friction as poss. When checked manually did not see any coil bind issues on the exhaust springs with this cam.
Any input on this will be appreciated
