the dome volume is the same 7.5 , the original piston dome .159 the 4 new is .170 , the original 8 has a .310 deep valve pocket and the new replacement 4 has .320 deep , they are the same weight , I feel they should make it right , but they trying to say it ain't no big deal that I should just use them

If this were for my personal racing engine and the piston weight is the same etc then I probably wouldn't care about it, nor would the engine know the difference (ie, any minute amount of difference isn't worth the time and trouble of replacement).

it ain't a big deal as long as it works. If that extra dome has room in the head it ain't a big deal Idea if it don't have room it's a very big deal! You could always cut it off .011?

While it is true the engine will not know the difference, it is still sloppy work.

If it were mine, not a customers I would check it, and if all good, run it.
