things I learned today about upgrading my ol R/T's heads: you can't count on anyone, even the manufacturer to keep anything in stock - plus, other companies make the same part cheaper, 1/3rd the price

ain't that ridiculous? And why? Because Edelbrock Victor heads are made in a way that Edelbrock says they can't use the factory stock intake valley pan gasket (the turkey pan) 

I will bet 10 bucks some grinding on the Edelbrocks MAKE that no problem. I am certain that Edelbrock realized that proprietary parts (this valley cover plate) would make them a lot of extra money if they decided that they could shape the head to block surface, or, the head to intake surface, so that this extra part would be easier to buy than a garage grind to adapt the head, or the old factory intake pan gasket, to fit with these Edelbrock heads
