stock oil pump for hp use

I always run the HP spring. I'd rather have the extra pressure. With good clearances, the stock pumps will go to 65psi, which is on the hairy edge of the performance envelope at 6500. If over 6K on a regular basis was in the plan, I'd run a HV pump. It's still limited by the original pickup tube demensions, (ID) but it will get more oil and therfore more pressure at those engine speeds.
