Reply to "Warning rocker arm pedestals machining on 4V heads"

The lengths of the valves are:
intake: Manley 11872 133 mm = 5.244 ''
exhaust: Ferrea F6124 128 mm = 5.060 ''

I haven't bought the pudhrods yet but if they are shorter the rockers will be in a wrong position and the displacement on the valve stem will be very important. The more the angle increases, the smaller the cosine.
