If they're the "Cobra" stamped covers those seem to command a lot of $$ on ebay.. I was hoping to find a reproduction set a while back when I started building my engine but nobody makes reproductions with the embossed stamp. Since they're no longer made, I guess the authentic ones are worth a bit. In case you want to factor re-selling into your maths.
As for the throttle body, 70mm is about the biggest I'd go with E7 heads, at some point you stop getting more peak flow and just wind up with a touchy pedal for the first half and nothing for the second half. I'm going to be installing a 65mm TB along with my X heads because for me personally driveability is more important than peak HP.
What I'm getting at is if the throttle body your local guy is offering is ~65 or 70mm that might be something to include/keep.. if it's larger or if it's stock, that would be less valuable in my opinion.
