I'm not sure, but I use the standard comp replacement lifters and have close to 500rwhp on the nitrous. It probably has more to do with how much spring pressure your going to run, but don't qoute me on that.

I don't know what the upper/outer limits are but my stocker with OEM lifters crosses the finish line at about 7300 and makes enough power to run 10.60's weighing 3250#. I don't believe that the lifters are the weak link.
