I picked up some ARP 100-1102 header bolts for my motor with ERA headers. However, the ERA headers have a really nice, thick flange and these bolts only engage about 3 or 4 threads at most. If I use a gasket I'll probably be down to 2 or 3 threads.

Does anyone know of another set number for an ARP set that has a longer threaded shank? Other options other than hardware fastners?

Thanks
