383 with zero oil pressure.

Mopar 367, yes that was one of the first things I picked up on while cruising the site. Thanks for your input. Will I be able to see if the pick up is bent, and will I be able to see if a lifter came out when I remove the valve cover?

Yes with a flashlight there are openings in the heads so you will be able to see all 16. It might be obvious when you remove the valve covers. Push rod stuck through a rocker arm or bent push rod.
