I've been running Intense 1.9 Stock/Modified Rockers for many years now and i've put nearly 100,000 miles with them in my car, so far so go. I later upgraded to 105# Springs/Retainers which upgrading the springs is an ABSOLUTE must for ANY 1.9 rocker build roller or modified, stock shift points or not. If you don't believe me do some research on ClubGP about spring failures with rockers. I was one of those guys, though I was lucky and cought it in time before potentially dropping a valve.
I plan on running my setup for the rest of my motors life, its got 170,000 miles on it, its too late to do a cam in it now.
Back in the day when I did rockers all that was availible was stock/modifed. Nowadays if I were to do a rocker build again i'd go with Yella Terra 1.95s Rollers honestly. But theres nothing wrong with stock/modified rockers either as you can see.....
