360 street build, please critiec

Reconsider the Chevy 1.6 ratio. Use 1.65 to achieve 1.6. The factory stamped steel are actually pretty close ratio wise. Magnum engines are 1.6 ratio. I have mocked up Chevy 1.6 on 318B heads. No matter the length of pushrod or how far up or down on the stud(rocker arm), the loss of lift was disappointing. Even considering the 59 degree lifter angle....
