[QUOTE="PALMER84ONE, post: 160228, member: 6"] Sounds to me like a valve snapped. Are the valves new? Are the valves china made? If you open the intake and exhaust ports can you see the top of the valve seats in the head? I am going to tell you what happened to a buddy when putting an engine back together at his shop. He was on the phone talking and heard a ping in the back of the shop, when he got back there a brand new head he was rebuilding with valves, springs, etc., was siting on the jig and one of the valves had snapped. Out of the blue, it just snapped and fell on the ground. Good for him it happened then instead of after the motor was together. Worth a look. [/QUOTE]
