Don't get it right, just get it running. 85 318 roller

I talked to the machine shop and they will boil the block for 3 days, run brushes through all the passages and install new cam bearings for $165. $70 for the block boil, $95 for cam bearings installed.

I didn't think that was too bad, so I am going to drop it on Monday.
That is a great first step. Ask them to measure the bores for taper and out of round while it’s there.
