OK so I dug out some old comp tool steel retainers I had on it before and tested them with the locks. 1.955 and with the +.050 2.05....
So the PAC retainers and Comp locks dont like each other, just like you said.
In PAC's catalog it says this about the locks...
We have standardized the spring retainer “cone style” to improve specifying the fitment
into a matching PAC Racing retainer.
That sounds like some Chinese garbled english saying we took 10 degree locks and retainers and made them not quite 10 degree.....
And then I noticed on Summit, the PAC R405 retainer is listed as a +.050? Really?
Its not listed as a +.050 in PAC's catalog......So which is it?
.050 +.050 still doesn't add up to .070
Put a little bigger cam in it I thought......Just change the installed height I thought......Silly me thinking this might be easy.
