Hey, grind a point on it and use it as a marking centerline punch for piston/valve cutout locations LOL.
Used to have same trouble with a friends' '70 Boss 302 (true boss) that ran in the tens 1/4 mi. The sodium filled valves had a tendency to snap in two. One came loose and piston struck it to sever rod, piston stuck high and the rod bent sideways to lock into its' paired mate turning a V-8 into a V-7..........the damn thing still ran 10.90s like that. The friend came back after two weeks saying he thought it was missing, started it up for me and I could tell one cylinder was not working, why he never yanked plugs I could not say..........needless to say he felt pretty stupid when motor was disassembled.
