I sent Steve numerous PM's regarding the valve covers. I bought near perfect sbc MP valve covers for $300 and cannot foresee these being worth the coin. The valve covers are not worth much because they are still produced today by Mr. Gasket (I think) and are readily available.
I think anything over $250 is too much. You'd get more money selling the emblems... which I told Steve I'd have NO issue taking off his hands...
