"According to him the "offshore" pieces are perfectly "flat". Being "flat" they cannot work correctly!"

What a crock that is. I have 2 sets of early hollow Johnsons in here for reconditioning and the screws were crowned, they are also HAMMERED FLAT.
Brand new, they will hammer flat in one dyno pull in a race engine.
The reason they have gotten away with this crap is, almost no one pulls the manifold and checks the valve clearances after a flathead is initially fired up.
JUST BECAUSE YOU DON'T BELIEVE IN THE LAWS OF PHYSICS DOESN'T MEAN THEY DON'T APPLY TO YOU.
The screws should be flat.
