There was as earlier post about fixing leaking exhaust maifold gaskets.
Cannot find the thread but did find the copper gaskets I have used.
They came out of the racing world to solve just this problem with FE engines.
SCE Gaskets. Part number 4134. Thy come in sets of 2 per package.
I think I got them from summit recing but the memory is not what it used to be.
I did not plane the heads of the exhaust manifolds as most of my cars are drivers.
No problems once installed.
Good Luck
