I run the (#2 and #4) grooved cam journals for continuous oiling and massage the drainback channels in the heads to make sure I get plenty of drainage back to the valley. Mine's a bracket car though but I think they're fine for a reasonable spring pressure moderate RPM motor like most strokers. There may be better choices out there but these seem more than up to the job I'm throwing at them.

The word I've heard about the Morel/Bullet design is they are essentially the same body as the Hydraulic Roller lifters converted to solids(which would explain the larger body/shorter pushrod), they seem to do really well.
