When the exhaust rocker just starts to open the exhaust valve. Set the valve lash on intake rocker at this time. Continue rotating the assembly and stop when the intake rocker starts returning from full lift. The lash on exhaust can now be set. Continue this procedure for the remaining cylinders. nothing is hitting the baffles.

this is not a fresh motor, the motor has been built for a few years ago.
