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

Get a piece of stiff wire (coat hanger) and check thru the oil holes in the main saddles to the cam bearings to make sure they got the cam bearings lined up. Then, use that same wire to check the oil holes thru the deck, down to the cam bearings to make sure they both line up. The oil holes in the deck are right above the 2nd head bolt hole from the left, when you are looking down at the deck on either side. You can see the passage going thru the lifter gallery, and can feel the oil hole in the bearing when you figure out where it is. If there is no hole in the bearing towards the deck, or the wire won't go thru, they screwed up the cam bearing install.
