The way I did mine, after coating all the main and rod bearings with assembly lube. I left my intake off, I pulled the oil pressure relief spring and plunger out and when I poured the break in oil in the valley, I poured some down into where the oil pressure relief valve sits. Re installed that. Then hit a couple of squirts of MMO in the cylinders through the spark plug hole, left the spark plugs out of the heads to keep as little friction on the motor. I spun it by the starter.....within 2-3 seconds at most, my mechaincal oil pressure gauge I installed at the back of the block at the sender jumped to life. I spun it for about another 5/10 seconds more to make sure it registered a good oil pressure value, which it did. Installed the intake and plugs and it was good to go!!!!
