The cylinders we had have plated were "ported" passed as cast. And what I mean is since the porting as cast is so low, to allow us and builders as much room and options for port timing as possible. We raised the exhaust ports to a "dune" port duration. Those are basically as cast with the port timing raised above what basically oem was. Plating one of our cylinders "as cast" is'nt something we'll be doing, nor what any builder would do. We do offer porting for an additional price. That would be done before plating to the customers riding style/mods/ etc. then plated insuring the best finish overall. The price of port work would depend how much or how little work the customer would want. We're thinking some where in the $250-$300 range for full drag porting and as little as $50-$100 to do minor opening or polishing or port durations changed to the customers liking. This would all be discussed with the customer at the time of purchase.
As far as our domes fitting that head... not sure. Ive never seen the inside of one but I'd imagine so. We do offer the machining of oem heads to accept our domes for $100.
