Some Break-in Ifo from Crane

Pretty much any single spring with a dampener is fine for break in and yes, additives are not evenly dispersed until it's been run a bit so break in oils are best. You just can't install the inner one if your cam runs a dual spring assembly. I'll add - I use the Crane cam lube specifically because it's a paste & doesn;t run off. You also should verify lifter rotation during assembly, and once the valvetrain is assembled - the fewer rotations the better before you start it so the lube stays put.
