Early Hemi Roller Rockers What do I have?

Guys,

Ive got these nib roller rockers for early Chrysler Hemi. What Brand are they? Titans? No markings on them. Can you guys help? Thank You!

 

They remind me of some that Rocker Arm Specialist made years ago but that is just a guess. I don't know if Gary carved his name in them or not.

Maybe a couple of better pictures out of the box? Are they roller (shaft) bearing? Shaft size?

 

Yes they are roller bearing and .875 shaft dia. Here are a few more pics.

 

I have a set of Canode's and Titan's and they don't look exactly like these. The stands do not have the relief on the end.

 

Ok thanks Dry Lakes, maybe they are PAW? or Hot Heads? I hope someone knows.
