push rod side clearance

[want2bfast]

hi to all, can anyone tell me what the minimum clearance is for the pushrod and the side wall of the head? I have shaft mount rockers so there are no guide plates. thx.

If you can see light around the pushrod, you are ok as a minimum. More clearance can be better - but the runner wall should be at least .100" thick.

If it doesn't rub it's good, coat a pushrod with a marker or layout die and see if it touches.
