Higher lift beehive spring recomendation for L92's
Trending Topics

I would like to use the stock L92 valvetrain parts (e.g. keepers). So with a dual spring wouldnt I need to change those parts? I am wanting to build a 6.0 with L92's with a .573 lift cam. I will be under 7000rpms. Just wanting to know if I can get away with a good beehive? And which ones.

The L92 intake valve weighs 108 vs 89 grams for the LS3 valve. They are cheap and interchangable so that is what we do, with no valve train control issues running up to 7,900 rpms.
There are Ti retainers for the PSIs but because the spring is so hard compared to the retainer the retainer does suffer some significant wear and lost material that goes some where ?? I have 4140 lightweight retainers made for the 1511s. They weigh 8.1 grams vs 5.5 for the Tis and should last forever. This combo works well on LS7 heads up to .650 due to difference in installed height on the LS7 head. Never had a failure-- and there are hundreds of race engines running this setup on LS1,2,3,6,and 7s. NASCAR Spec motors and others. Granted, fewer with the heavier stock L92 intake valves but I have run those on a previous 402 well beyond 7k on numerous track days.
