<VV> Snap rings for lifters

Has anybody replaced the bent wire retainers in a set of new lifters with 
real snap-rings -the kind that demand a set of snap ring pliers to 
install/remove? I have, at times found the bent wire pieces in the pan, never a 
snap-ring. Is the groove in the lifter shaped correctly to receive a snap ring 
edge, or is it "too" round, made to accept only the round shape of the 
wire. Any thoughts on doing this? - Seth Emerson 

============== 

I would not install a hard working snap ring in a groove that was not the correct profile. 

Grooves for useful sizes of "truarcs" on pages 2 and 3 here

note that the depth of the groove and maximum groove corner radius are specified. 
As are the max radius or chamfer of the retained shaft (R Max or CH Max ) with the maximum static load. 
I think a dynamic, or worse impact load, would be much less. 

spirolox generally have the same groove dimensions as truarcz\
