I am with you on the fuel efficiency thing. Screw it. I wish I had an answer or information for you, it sounds like you could build a killer motor with those heads.
But in all fairness to the other Lateral-g members here in not getting back to you, it had only been two days between posts. I have had weeks go by without an answer, but when I got it, it was right and worth the wait.
Best of luck with the build. Post up some pictures and dyno results if you can. I'd like to see it all done.
