the engine is a 59-62 last four of the casting # is 9925
it's a brand new block never been built.
the plugs i'm asking about are the ones at the front and rear of the oil galleys.
the ones on the side I assumed are for the external oil filter lines which I plan to install
the 54 truck manual mentions the plugs one the ends of the block but doesn't say how many.
the obvious ones are at the ends of the galley's on both sides I just don't want to miss one.

thanks guys
