I don't even know if this is possible, but can lifter brand be identified strictly from a photo????

I have these for my stock build. What brand are they?

The GM ones I installed in my motor did not have the dimples in the top were the push rod seats... So i do not believe yours are GM... I have seen after market lifters with the dimples in the top, as to whos I,m not much help... I think I have seen NAPA and Carquest with that style of lifer... Tom G
