L83 Cylinder head locator

Does anybody know where I can get one of these for a Gen V, L83 block? Don't know the correct name for it, but it locates the head on the block square. If it is not on there, the head can get crooked and the valves will hit the piston. I forgot about it since I am using studs instead of that one funny looking bolt. I put the heads on and was checking to make sure all of the rockers were opening the valves---clank! The holes in the stock head are a bit oversized and will let the head mount wrong. I thought I put the DI pistons 180 degrees off. I can tell you that if they ARE 180, and the piston is TDC, you are not bolting on the head.

Back to my question---where can I get one of those split roll pins? THANKS
