Does the k1078578 replace the 84679-aa flush valve assembly?

Suggest you ask Kohler directly.

what is diameter of connection holes in kohler k1078578 flush valve?

Don't know but genuine Kohler part should work.

8.5 x 10.35 x 4.95 inches exact measurements

What is the difference between this and 84996 ? Also, says "constructed of brass"???

The 1078578 and 84996 are the same- the 1078578 is the current part number. Either one is fine...the 84996 has probably been sitting around awhile but that is the only difference.
