1. I spoke with Zach about a week ago and he said the old PRCs would drop in without any machining if I was already using the 918s. Does this still hold true for the new PRCs?
2. Also I was told that Comp OEM lifters would be able to handle the spring pressures of the old PRC. Will they handle the pressures of the new ones as well??
3. Have any of you guys tested them out, do you think they will perform as well as the old ones on a boosted car. Zach told me you use the old PRCs on a TT vette
Thanks

What he said. Also, is the install height different on the LTX vs. LSX heads stock for stock with supplied retainers? What are the dimenssions of this new spring and retainer? I want to know if it'll fit my application, because the seated and open pressures certainly do.

They should have very similar life when compared to the previous spring. Look for alot more spring options available soon, I have several ideas working to improve the ls spring world! Spintron & computer testing is helping to give us several ideas on how to make a better valve spring! Look for more to come from PRC very soon!!
