First, this is not about quality, shipping or delivery. Comp cams products are excellent quality parts. It is about lack of info as to fitment. If you have a C5 corvette LS1, these rockers will NOT fit under stock valve covers. To use them you need to get taller valve covers which have the breather -oil fill reversed so the rocker covers no longer fit, requires purchasing longer plug wires as the coil packs are also raised, relocating vacuum lines to the valve covers. It can be done but the top of the engine will no longer look factory original. If That is ok by you go for it. For me it is too many mods and added expense for the few horse power gained. I am not knocking comp cams. I have used their products over the years and never had a failure.

I installed on a LS1 c5 corvette. The rocker arms come with new bolts. Torque bolts down and you’re ready to go. Very noticeable horsepower increase. I also checked the run on clearance and it was in spec
