Why do advertisements say "Not for factory hydraulic rollers" and some say "for hydraulic roller cams", and some don't mention it either way?
All I want to do is buy a kit thats not ungodly expensive without any hassle. Cloyes makes a heavy duty true roller kit for about $30 but it doesn't specify if its for roller cams or not.

 

Post up the part number.

There's a difference related to the cam gear, because of the roller cam. GM added a retainer plate and cut down the end of the cam so the cam gear is a little different between the roller and non roller.
