Since I switched my new heads I've been haveing a little trouble getting them to stop from rattling. I've only turned them 1/4 turn and may just need to turn them 1/2 to get them to stop. I was wondering about useing crane's nuts as they have a set screw to keep them in their place.
Did you have roller rockers before ? Mine are pretty loud. Doesn't really matter how far you turn the nut. As long as the clip inside the lifter doesn't touch the plunger. Basically just need the compress the lifter about .010-.015
