Yes they are Comp lifters, or at least built from the guy that makes them for Comp, and they pushrod oil and do have the offset intakes to straighten out the pushrods a bit...

They also oil the wheel to improve life expectancy, and the oil feed holes are parrellel to the wheel axle to restict oil to the top a little.

Got them from Brian and IMM ( OU812) I have 2 sets and will rotate them out after 150 runs...

I believe i have maxed out these heads, but a dry sump and a tunnel ram might pick it up a bit??

Should run 8.70's at 4,000 feet DA in my 2,850# Cuda if i can keep it hooked with the 10.5W's.

Good luck with the build.
