Comp 918

From what I've seen both here and on LS1Tech even the new silver Comp 918's are breaking frequently enough that I wouldn't run em. The PAC 1218's have been proving themselves to be reliable though

They have become HIt and Miss. PAC Dual springs have been the new favorites. At least with dual springs even if one breaks there is another there to help keep your block good.

Not all the time. I have seen the duals still do some bad damage when they failed. IMO anything under .600" lift should not use dual springs as they are stupid over kill and the extra weight on the valve is not necessary. Just my opinion.

Custom spec Patrick G from EPS, havent gotten it yet. Just putting together a cam package. I was going to to a package deal from EPS with 918s but I keep reading about 918s breaking, even the new batch that supposedly has fixed the problem.
