Bent up stuff

We rotated the motor by hand and no binding. We also torqued one head and used play-do to clearance check the valves. No contact and .380 clearance.

There is no way in holy hell you have .380" clearance. That's over 3/8"! No way, no how. I am tellin you sure as ****, the pushrods bent because valves and pistons occupied the same space at the same time.
