My Experience is with the Full roller aluminum rocker arms from Procomp
1. They don't come clearanced for the valve cover bolts on a BBC
2. The slots are not wide enough
3. With the supplied locking nuts they will bind at anything over .600 lift
4. After running them for less than 200 miles I found that the roller tips were chewing into the body of the rocker and there is nothing to keep them from doing so.
Like many people, I was running short on cash when It came to rockers I wanted to go with a roller rocker and came across ones like this...

I did not purchase these particular ones but ones just like them. AND they claim they are the best quality on the net.
Don't get suckered out of your 105 bucks plus shipping.
Disclaimer: This is not a statement against the folks at J&C cylinder head exchange I have purchased heads from them before and it was a good experience. I just used their ad on ebay as an example.
I will submit some pictures soon but please direct anyone inquiring about these rockers to this thread.
