about the mis-match on water pump,is that a LA timing cover with a magnum water pump?

I know the LA t-cover will swap over to the magnum block and vis-versa. the last gasket set I had I noticed the t-cover gasket was the same for both blocks. 1 bolt hole is different location.IIRC

water pump gasket was 2 different styles and looked like they would not swap.

so would a little machine work be the fix for mixing the LA/magnum WP and t-covers?
