Yes and they are based on the NASCAR/Drag Racing type of "super seven" design. Preliminary testing looks very good and production pieces should be available very soon.
Matching retainers in chromoly and titanium will be LS1 specific and will have to be used for best results.
This has worked extremely well in my Ford racing customers so theLS1 guys will be very happy.

I bought a set part# 13098 locks from Manley, same angle as the stockers but they're machined instead of stamped and they're heat treated.
If the Super-7deg locks had been available, I would likely have gone w/ them just for the extra margin of safety.

These are exactly what I'm looking for. Do you happen to know what springs the retainers fit? I bought some 918s/Ti retainers to go on a new set of heads.
