Anyone have an aftermarket oil-pan for street strip?

Do you have headers 1-3/4 SLP?

Reason: If I go down the track just past the 1/4 mile mark the pressure drops to near zero.

The oil pump is a high pressure/volume pump and runs off the guage most of the time.

Also, I have AFR heads. I heard about drain back problems.

Any insight would be appreciated as well as part numbers of pan/pick-up.

thanks
