If your 525 is a gen 6 might want to check the accessory mounting bolt holes in the end of the heads, chances are they’re 7/16 fine thread, and the darts will be 3/8 course thread, it’s easier to drill and tap this when the heads are off vs. assembled.

I'm so confused on gens at this point lol...it does not have the fuel pump provision...its has the pump on the water pump and it did not have the cam retainer plate..has the button on the cam...the heads are already assembled and on unfortunately...the valve cover gaskets were the last piece of the puzzle besides smoke checking the engine to look for leaks

BBY, that is a gen 6.........Im pretty sure my Edelbrock 525 heads are 3/8 on one end and 7/16 on the other.....leave it to Mercury for the 1 off head design.

Does it have an aluminum timing cover with 6 bolts? If so, it is a gen 6. If it has a cover with 10 bolts, it is a gen 5. If it is in fact a gen 6, I would advise against running a cam button on the aluminum timing cover. The retainer plate is a much better and safer setup.

Call Dart?? they should know what fits if their heads are odd shaped

You have to machine the drip rail down to the same level as the stoppers on the outside of the bolt holes... at that point they'll drop on and seal like any other cover... been there done this got hat and T shirt
