    I use WD 40 on the rings and cylinder walls.

    I just did the break in with a solid lifter cam, I took out the inner spring and ran the BR40 10-40 break in, went great and after a week of driving around I put the inner spring back in and then went to the Driven 10-30 oil. 50lbs pressure at 3 grand.
