If they were burnt off thats one thing.. most times
when they break off they break at the weld point ..
tell us if they are burnt off... lets see a pic..
also if they were hit by the piston they would be
bent down
EDIT
I run that same plug in my street/strip 416 with
10.4 compression.. also make sure you didnt put in
the AR3924... thats the short ground strap for racing
