Thanks Crizila, that was the kind of information that I was looking for. I hate to be the Guinea pig!!

We are looking at all angles, including having someone fabricate custom valves for this combo. The Hughes valves are a step up from anything else that I can find when it comes to installed height and such. Even with that, there could be some improvement for what we are planning to do, so we may opt in the end to go with a custom set of valves. Time and money sure will dictate that some.

Thanks for the replies.
