No, unfortunately, the later Ranger DOHC engine is basically a Mazda engine, so short of swapping the whole engine, it wouldn't be an option. Surprisingly, a Volvo B234 twin cam head can be swapped onto your engine, but it does require quite a few custom parts and some machining to complete the swap. I think for the $$, Esslinger engineering or BoPort racing engines can build you a single cam head that will in most cases, out perform the Volvo head, as good as it is. There are quite a few turbo Pinto's running around, that might be a good option for you as well.
