If you want a cheap way to see those Hemi valve covers under the hood of your B body, a fairly stock early Hemi can accomplish that at a reasonable cost. But it's impractical if you are going for high performance. The Gen 2 Hemi is so superior to the early Hemi in so many ways. It's almost impossible not to make 700 horsepower with a nearly stock, naturally aspirated, stroker Gen 2 Hemi build. With an early Hemi, you will spend a lot of money, spend a lot of time chasing hard to get parts, and work really hard to get 700 horsepower.
