I think you'll have to custom make a 12-point wrench to work on those bolts. Not impossible, but the hex head bolts might be easier. Otherwise those look correct.

depends on the flange thickness.... anything 3/8" or thicker needs 1" IIRC.

I agree, the flanges on the Pacesetters are kind of thick. I originally had 3/4 inch ARP header bolts but they just didn't feel like they had enough bite so I swapped them for 1" bolts instead.

how do you figure? I got my breslin's in with a 12 point wrench no problem. They were actually a lot easier then the 6 points, because I could make a longer rotation.
