Default Header bolts

Can someone shoot me a link to a set of header bolts that have the allen fitting on them? 12 pointers are not working out so hot. Can't seem to find any.

The 12 point bolts I have from ARP aren't clearing the tubes.. I have 3/8 though... you think 5/16 will make that big of a difference?

Depends on the header used. 3/8" ARP's work great for Hooker LT's.

Even then the 5/16 are much easier. I have them on 2 cars and they work flawlessly and even on clients cars I use these on every set of headers that I install. I.e lpps, hedman, hooker and knockoffs
