Ours are 5.7g each. Not sure if you are going to find a lighter one.

Comp Cams tool steel retainers are 2 grams heavier than their Ti stuff. For cost and strength, I don't think you can beat them.

2 grams could make a big difference in valve train stability. The lightest possible would be best.

to Original Poster: The setup i have used in the past:

PSI-1511ML springs and Katech retainers = .700 lift capable on LS7 heads, retainers weigh ~5grams, lightest valve spring setup around.

PAC Titanium retainers-----------5.7 grams
Katech Titanium retainers--------5.2 grams

PSI-1511ML Beehive springs------65 grams
PAC 1518 Beehive springs---------62 grams

Thanks Guys!
