Each kit includes dowel pins,

nents, woodruff keys, cam eccentrics, etc.
American-made bearings for new or
used blocks have the surface
characteristics of babbitt and will
withstand high valve spring pres-
sures. Use standard performance
bearings with hydraulic or solid lifter
cams, or high-performance bearings with roller cams. Most are and less friction; some are available in .010", .020", .030", and .040" oversizes. Specify size when ordering.
