i got to thinking about it and and the stud itself doesn't but the threads do so i just called the tech at ARP and they said the only thing is that it needs 1.5x the thread width of thread engagement, dead space doesn't matter.

got to building the motor and realized that the stud does bottom out in the block.

According to the Corky Bell's book, bottoming out is the desired effect

VW p.n. 204-5402

about $130, which is a high retail price, if you know anyone in a shop or if you have an wholesale accounts you should be able to get them for about $80-$90
