TOTAL valve lift is Lift at Cam times rocker ratio

For instance, a 0.320 lift at cam with a 1.5 rocker ratio equals 0.480 lift at valve

your 212 / 222 number is the duration and has nothing to do with the lift

your 435/460 is probably the lift with 1.5 rockers if this is a small block chevy engine ....making the cam lift 0.290 and 0.307. The first number is for the intake and the second for the exhaust.

If you have a calculator, you can multiply the cam lift times your rocker ratio.

Then, you should check each valve at the lift to make sure you dont have spring bind.
