If I wanted to, put in some stainless steel roller tip rockers, but stay away from aluminum rockers. The big key is to follow the cam break in instructions to the letter and you'll have years of trouble free running. I thought about going to a roller cam and lifters, but I already had this cam and lifters (left over when my previous truck was stolen before I finished it up) and have blown right through my initial budget.

I would make sure that the springs you have on the 2.02 heads are not too strong...follow comp cams spring pressure exactly or your cam will go flat.
Especially if they are dual springs. If so remove the inner springs on start up and then reinstall after cam is broken in.
