If it's together, then chuck it in.

If the lifters are put on the same lobes they came from, then that's no problem.

Get her going & IF you used plain or moly rings, drive it with a fair amount of full throttle in bursts from 2500 to 4000 rpm, drop the oil & filter after 150 to 200 miles, let her cool, then run through the tappets. Add new oil & filter & it's run in. Drive normally.

Oil: Make sure it has enough ZDDP for the cam.

Filter: I use 1 pint filters from other manfacturers. For breaking in I like to use genuine Nissan or Toyota oil filters, afterwards, the typical Ford filters of decent quality.

What cam & springs do you have?

What do you want from this engine?

Do you have something in mind for a future engine?

Next time it's apart, toss the B18 rods & upgrade to the early B20 rod, which is a direct swap, but are beefed up around the rod bolt area.
