I'm going to put in an F13, and wanted to know if the Comp 918's are good enough, or if I need dual springs? Which will last longer? The lift on the F13 is .595/.585, duration is 230/232. Since the F13 power band tops out at 6800, will I need to upgrade the lifters?

The 918's are working for some with no problems but we recommend that you use a dual spring with the F13, the PRC dual kit is actually cheaper than the 918's and retainers.

The manley springs are not polished.How can this be better quality?All of them are made of good material.The PRC springs are top quality for the price.
