Default Dowel Pins missing from head/cam housing?

Is there supposed to be two alignment pins on the PS of the top of the head to align the cam housing? I noticed my head/housing have two holes on the PS where it looks like alignment dowels would go, one near the front, one near the back.

If so, anyone know where I can pick up a couple? They've got to be pretty standard, size-wise?

5/16 x 1/2 is what I used after some head work.
You can get them in different lengths just be sure to measure so as not to go to tall.

I think I found mine through Summit.
Let me know if you can't find them and I'll look for the numbers.
Cheers

HA! I knew something was missing. I tried to snug it down and it was going slightly crooked.

I would appreciate it if you can find it. I spent some time on summit's site, there's 0.310, 0.313, I really don't want to get the wrong ones, I'd like to hear it make some noise this weekend.

Places like Ace Hardware carry steel dowels as well. Jeff provided the dimensions.
