The early Chrysler hemi's have been popular with hot rodders and drag racers for a long time, mainly the 392 and 354's. But as the 392's and 354's get harder to find and more expensive, the other early hemi's have been gaining popularity. I wouldn't say a Desoto hemi is worth a lot, but I'd say its probably worth the $600 the seller is asking.
Just in the last year or so I've seen new intake manifolds being made for both the low and high deck Desoto's. They still aren't worth a ton, and they're expensive to rebuild because of the parts. But a 330 or 341 Desoto can make just as much power as a 331 or 354 Chrysler, and I would expect their value to climb as early hemi's get scarce.
As far as the hemi covers on the Cuda, all I'll say is, its a 340 4 speed Cuda, why does it need fake hemi valve covers? :dontknow: Sorry. Just my opinion, and we all know what opinions are like.
