Chopped 40, you can see photos of the Stude on my site...geocities.com/garyhartracing...I did not drop an exhaust valve through a piston, as previously thought. The valve pulled the guide down out of the head and the valve got bent, just touched the piston. We are giving .004" clearance on all the exhaust valves. I am assemblying the engine now, will run the car on a chassis dyno this winter to see if it will hold up to 7000 rpm for a good minute and a half.
