Pushrods

Hi! Thanks for great response!
I guess i should try to find out what kind of work that has been done to the head.
I know it´s milled,but not how much. The block hasn´t been done anything about.
If i look at the rockers and the adjustment screw,those screws are all as far as they can go,almost....
I can drive the car for some miles,50 miles was the latest trip before the pushrod gave up.
