Ratio rockers with snap ring retainers?

[QRP]

Anyone ever use a set of rockers with snap ring retainers ?
Thinking of running these with a stock cam & single H.D. springs.

I think it was Art Thraen that used to take stock rocker shafts, and make the grooves cut for the stock clip into a full circle to accept a circle clip. Maybe these are simply some ratio rockers installed on that type of shaft. I don’t think you would have an issue with a low lift cam, and single springs, but maybe someone that has found the limit of a circle clip style shaft will chime in.

As I recall, genuine Sig Erson ratio rockers used snap-ring shafts. Those don't look like Erson rockers at all but maybe it's a clue.

My boss told me I need to work on my mutli-tasking. So now when I use the bathroom at work I surf The Samba on my iPhone.

Thanks for the input guys, shafts look to be original to the set and not modified stock ones. A while back someone told me they were early empi. They do seem to be in good shape.

Q,
No definitive answer yet, & the shafts could be anything - it may help if we knew their diameter. Could ya measure them?
The rockers do appear forged, & sport the same rough profile as those seen in the thumbnail image for GB 412-145:

A quick caliper check on the shaft measures. .707 dia.

My Pauter rockers use cir-clips. .615 lift and CB VW650 springs. Have also used them on cam with same lift in Comp Eliminator heads with Chevy springs @ 600lbs over the nose.

Art Thraen used to do that circlip mod as well as Sig Erson rockers had them. If you decide to run them safety wire that clip so it does not come off when running!

Forgot about Pauters, that reassuring to know.
And safety wire is also a good idea.

Thanks
