You state that should you want big power out of your ZVH you can change the rods and push for 300+ but then state to get the same power out of a CVH all the internals need changing which is not the case.
I believe that Christian does 300+ on a standard virgin crank on his CVH and I dare say that few ZVH's are doing 300+ with the standard pistons and compression ratio of the zetec for a long time... which would suggest that the rods, pistons and compression ratio would require attention in both cases not to mention head and cam work
If your comparing the prices of doing a ZVH from scratch with all the machining work, the additional extra parts to make it all fit against a tuned CVH the bang for the buck imho is quite similar.
If I was given a standard RST and a small budger to modify it, I would do good intercooler, head, cam and chip any day over block change because untill these parts are of high quality and performance you will never ever see the performance offered by the block imho
