350 Stroker to 383 with a 400 crank, Crane Cam, Q-Jet, single 3.5" exhaust..
I'm not picking up on the block as to: what size, is it cast iron or aluminum, what heads are on it, what was the original engine size (cubic inches) what are the current heads from (350, 5.7, 400, etc.)?

I've found mystery coolant migration into the engine oil from mismatched head's on the block.

I apologize for any ignorance, but I'm not clear on the project as stated here.
