Valve cover clearance with Hughes roller rockers

I ran Hughes 1.6 rockers with Edelbrock heads with factory 340 valve covers and had to hammer the baffles for clearance. Fel Pro makes a double cork gasket with a piece of sheet metal sandwiched between, I have a set in the shop if you need the p/n.
Yeah if you do not mind getting me a part number for the gasket, Thanks..
