About all of the Manuf in Napcar use a 2 piece cover with no problems. They are all Billet though , not a Casting . We made ours with a .375 wide flange and dovetailed in a .080 Viton Oring . No Leaks ever.
But the dry sump pumps pull 20-22 inVac in the Crankcase , You cant even pull the damn things off with no bolts in them when the engine is running !
Im sure someone makes a good BBC 2 Piece cover , but the are gonna be pricey!

I used to have the KE two-piece valve covers and they were GTL (Guaranteed to Leak). Switched them to the Lightning Performance ones a couple of years ago and they work very well. The KE ones are junk....
