FYI The engine seal kit comes with the bolt grommets for the valve covers.
The oil pump should not need replacing on that motor as of yet.
I would suggest timing belt, front seals, water pump, atf change, differential oil change etc at the same time you are doing the HG replacement. Also, be sure to have the heads checked at a machine shop. The money you spend on doing the service properly will greatly benefit you versus having a car that develops premature leaks with a nice shiny new hood.
The ebony you are looking at could be just as much or more issues than your Pearlie.
