Leaning toward the Comps right now, I have fairly fat springs 1.53" IIRC. Hate having to change pushrods though.

I did notice that when I had the old Cam motion Cam which was designed for the IROC 358" Motors, the #2 and #4 cam journals were grooved and they moved plenty of oil to the top. I have an 8 quart Milodon Dragster pan on it so adequate volume/baffling/uncovering the sump was never an issue even with the extra oil up top.
