Youre correct you do have plenty of clearance at .140 & .095 at edges.
My clearances with recent check were 0.058 to 0.065 so I opted to go with that as ideal being 0.050. With your engine I would perhaps reduce the clearance but its your engine.
Also depands upon what head gaskets in use, copper or composite as crush on these can differ a lttle also.
