Stock valve springs? Red flag!
By Royce - 02/07/2004 7:49:24 PM; IP 67.72.178.141
Those springs are over 30 years old and have umpteen thousand miles. They probably were binding. Or they could have not enough pressure to close the valves quick enough to avoid the exhaust valve being chased towards closing by the piston going upwards.

Did the spring break on the valve that hit the piston?
