That's not really true. Studs serve many applications and require many different strengths, grade 3, grade 5, grade 8, aircraft, to mention a few. The stainless all-thread I used exceeds grade 5 stength and the 3/8-16 stud will take about 50 lb ft before it achieves it's yield point. ARP makes a particular stud and it can serve a multitude of different applications and strength requirements. It makes sense for them to make a stud that can exceed the strength requirements of many applications, intake bolts for one. It reduces their required product lines. In addition, cutting them to length does nothing to weaken the stud. You're not talking required grade 8+ head bolts here..
OBTW ... the OEM intake bolts are only grade 5 too, nothing special.
