I thought I would update. I called and they said the stock ones would be fine for my low RPM engine. However, after looking at it, I don't think so. I don't want an .125 of slop in there. When I assembled the heads you could see how the springs were not centered under the retainers. I don't want to drop a valve for obvious reasons.
Is there anything special about Mopar retainers for BB's or can I just order some 1.5" OD retainers from comp such as these?
Comp Cams #249-744-16
Any recommendations?
Thank you, ROB
