troubleshooting oil pressure

I did make sure that the pump did seat flush with no interferance after getting the correct rear main bolts from ARP, this was a small hang up during my build. But ARP sent the bolts for free and quickly once I called them. It seems to be an issue they get calls about often. So they had the fix already figured out. Seems like they would change the two bolts out before shipping. But they were quick and professional.
