Thread: Valve Spring Question

Tweet

Have an 84 truck engine all set to put back together but I'm not sure if I should leave the rotator on the exhaust valve springs. Going to have higher lift cam: .420/.443 I have the new springs but it appears that the installed height for the exhaust springs will be less than that of the intake springs due to the rotator on top of the spring. Anyone have any advice on this. Should I just get new keepers and locks and throw the rotators in the garbage or can I keep the rotators without running into coil bind with the new cam. Thanks. Steve

You got it.
Get rid of the exhaust rotators.
