Which Sea Foam product for priming an engine? [SOLVED]

I have a remanufactured engine (supposedly) on my engine stand, i have found sludge in the oil gallies and oil pressure relief valves. My engine is 90% complete and cannot disassemble… i have used an electric drill and tool to prime the pump (distributor port). i have the engine primed but the new oil is cloudy after draining…. My question is; what do you recommend i use as an additive to prime my engine again… I was gonna add more straight weight 30 oil and Seafoam and run the prime (drill) again to try and clean the oil gallies better before i start the engine and run at temp ? rpm…. By the way, the engine builder blamed the sludge on the hot tank chemicals hes not able to use any longer and the sludge is only a small amount…. Sucks for sure
