I used the stock wimpy Magnum valve springs for my break in, then switched in the HP springs after 500 miles or so. If you do this, just be sure to check for coil bind with your cam, and don't rev it too crazy with the stock springs.

I used moly paste on the lifter lobes and the bottom face of the lifters. I put pure motor oil on the sides of the lifters and made sure they spun freely. Put the red Permatex Ultra slick on the rockers.
