I have Crower Stage II cams with an advertised .559/.570 lift and my heads have Comp Beehive springs that are advertised to work with .550 lift cams. Will I be pushing my luck with these springs? I really don't want to change them out.
You should change the springs for a set with at least .580 lift capacity. That'll do what you need and be big enough to handle a little variation in installed height.
