The springs in the heads are rated for .575" lift, and the 268 cam is spec'ed for .454" lift, so no problem there. A couple chevy guys from way back, one of whom has been bracket racing his 69 Camaro for over 20 years, recommended to me years ago that for a street engine that isn't going to be seeing high rpm I stick with hydraulic flat tappet lifters and good quality stamped rocker arms. 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.
