I bought a used on3 kit, have my stock header bolts from my old headers but the turbo flange is much thicker, almost 3/8s. The hardware only threads in 2-3 threads. Does anyone know of a hardware kit slightly longer and retains the 12 pt heads?

I could always run to local hardware store and pick up some grade 8 bolts few mm longer, but not with the 12pt heads.

ARP header bolts. I'd have to measure them to get you the length on it, but it's basically just a longer length header bolt. Find the length you need, and order the ARP set.

The stock length is 3/4, arp come in 3/4 but no longer I saw. The stage 8 does come in 1 inch but are pretty expensive, time to pony up some cash I guess.

Summit has a huge selection of header bolts. I have gotten 12 point 1" long header bolts there before. Not too much money either.
