yes, there no magic to the head work on a stock DS, there is not much you can do but clean up as stated in earlier post unless you are going for all out drag racing. The ports come big stock and just need cleaning up with some work on the valve guide journals. It is little work for great gains if fed the right amount of air/fuel.

there are all kinds of bowl bending to be done on the DS. you can get alot more low end withwork done to the bowls. make it flow tons better when the value is just opening. you always get what you pay for unless you done it your self.

Anyone milling the head or just the runners? What are the benefits from the larger valves once the head work is done?

bigger diameter allows more fuel air to flow in the same amount of time.

Snake:

How long is Ron Wood taking to do your head? What are you expecting the difference to be with the head vs. before (without the head?)

What made you decide on the Ron Wood over others?

Are you running the 11.5:1 or 12:1 piston? If 11.5:1 are you running pump gas?

Anyone have trouble with leaking head gasketts with a Ron Wood head?
