i just bolted them on and torqued them to spec (which i believe is 22ft/lbs). no problems here...
motor makes 500h.p. and similar torque and has seen 7,000rpm a few times. no noise, no problems. im using patriot heads.

vinci/crane rockers rely on stock or most aftermarket lifters. comp R are he only one's i have read that only want .004"-.006" preload. so, if you have comp R lifters with vinci/crane rockers, you'd use the preload for comp R lifters.

They also have be proven to accept more preload with smaller lift cams.
