The valve springs are 1.500" doubles, 225 on the seat and 700 over the nose. It has a good crank, scat rods 6.800" rods, standard cam journal, economy roller rockers, .080" wall push rods. For street use, I would expect a normal high performance service checks.

This engine would be a perfect bracket engine.
