Blueprint or CAD file for small block mopar head bolt and dowel locations

Does anyone have or know where I can find a blue print or CAD drawing for the location of the cylinder head bolt pattern and dowel pin location relative to the bore centers? In other words the top of the block or deck where the head bolts up. Thank you.

I have a set I brow beat out of Arrow (IIRC) as they are damned near impossible to get. Why the morons at Chrysler refuse to make this stuff easy to access I can’t say. But the road blocks are real.
