If you are using springs that have over 450lbs of nose pressure, or a steel cam, it is recommended to machine your block to run bearings on all seven journals. Use HC-1 on stock size cam journals (2.124″) Use HC-2 on large journal cam Vincent (2.165″)

Both the HC-1 and HC-2 use 2.333″ (+/-.0005″) cam bore
