I've once found this image made by Doty Man. for a BigBlock Mopar which I saved for when I decided to make a torque plate.
Not sure of accuracy, as the torque plate plan never got done.
I did make a vector-trace in Adobe illustrator at the time from a steel headgasket but never confirmed it as been accurate.

Ford SB is pretty easy, everything is symmetric. 4.380" x 4.240" with the cylinders centered in the bolt pattern.

LS is similar to the SBF, all symmetric 4.400" x 4.331". Bores are centered in the head bolt pattern.
