drag racing stud regulations

Q I normally run 1.060-inch t-nut chisels. Looking at shovel point push-through types, but they come in a 1.18-inch. Anyone know if that length will pass tech with the Woody’s angled backers?
A No. The Woody’s angled plate will not put the stud on enough of an angle to clear the tech gauge, so it won’t be legal for ISR drag racing with ¾ of an inch penetration rules. – Jason Houle, Straightline Performance
