273 guys..Heads up!!!!

Thanks guys! & i honeslty couldnt think of anything else "steel" that woulda got in there other than the gasket. id never have guessed my home brew blocker would ever end up in any cyl! ive had the same ones in my ols 340 for 6+ years & never an issue & i built that engine to take the severe abuse i dished out @ it until i sold the car last summer. This was the last ting i thought would wind up in a cyl!!!!
