if everything is done right theres no reason to have the lines running up to the top. All of the motors that I've had, never had any with that set up and all were great.  Biggest thing I would say is getting the cam bearings in correctly, properly aligned,  and have a rebuilt set of rocker assemblys that don't have any old gunk in them to get into the "new" motor. The other thing I have done and I think others will comment on this is to fill or put oil in the rocker shafts before firing the motor.

So, put a 1/4" socket on a long 1/4"-drive extension, and run it with a 1/2" drill motor.  I would NOT use a battery-operated drill motor.  The oil pump produces 40# pressure, which tends to take your drill motor for a ride.

While building up pressure, check your pressure gauge.  (Really, you don't have to since you will definately FEEL the pressure building.)  While still using the drill, run the engine with no spark plugs for about a half minute by energizing the starter.

If your rocker covers are off, you will see oil come out of the rocker arms.  Install plugs and your distributor, and run the engine at or above 1,500 rpm.  Remember, the cam is going half that speed, so the idea is NOT to run a new cam installation too slow.  In order to seat piston rings, you need to 'load' them while driving.  Hope this helps.  - Dave
