Thanks JPH. I’ve been concerned because I have the PAC springs and Ti retainers but Comp literature seems to recommend dual springs for all XER lobes – I can’t find a specific recommendation.

My cam is a bit larger then that with chromoly retainers and PAC 1518's installed at 1.75" and have no valvefloat problems. Stock lifters, and stock GM valves(not lightweight LS6 valves) are what i use as well so I don't think you will have any problems.

Katech uses some of our higher end stuff for their C6R program.
PSI was started by ex-PAC guys. Just a fun fact.

round wire vs. ovate wire
IMO PAC springs are lot easier to get ahold of for a competitive price too, PSI's distributor is a small arrogant group out of NC <rant off>
