Have you seen the article in the Jan/Feb 2001 issue in the 12 Port News by Robert Duggan about his 261 build and 848 head work? if one wants to go back to what the racers were doing in the early fifties, there are the books by Roger Huntington and California Bill.
I'm very interested in seeing what you and the CNC-Dude (a great addition to our little band!) do with your heads, as I have an 848 and a couple of 850 heads with which to experiment in the near future for my next 261 build. One of the major problems with the stovebolt heads must be the sharp radius that the intake flow must negotiate as it turns 90 degrees to head towards the intake valve.
