I had to use two special short head studs i got from a hardware store, the top row outer two "since i couldn't use stock do to the ramhorn" and one broke and the other fell out. i used stock bolts for the rest an seemed to be fine. I was wondering if theirs special studs or something you high hp guys are using?

 

are you saying the flange is to fat or to skinny
