Guys I have a set of AFR 195 and stock 1.5 rockers on them...Cam is a comp XE284h..
I got back form the power tour (only 850 miles for me) decided to check to make sure all rockers were tight and run valves for a piece of mind.. I removed a couple of rockers and looks like they are rubbing ever so slightly on the spring retainer. Why??? Not sure if it was all of them but I believe the one I seen was an intake. There was no gouge but a small shiny spot.. Any ideas?? :confused:

I had this problem, you can read through my post, (http://www.chevelles.com/cgi-bin/forum/ultimatebb.cgi?ubb=get_topic;f=9;t=015546) it has most of the information you are looking for, I've since come to realize comps conical springs would also remedy this problem.
Best of Luck!! graemlins/thumbsup.gif
