Not only cheaper but the forementioned dyno tests showed the stock 194 head didn't raise the power as the compression gains were offset by flow restrictions for a net HP loss. So the myth is exposed.
Was there ever a dyno test w/a 194 & 250 stock head w/standard size valves 1.72" intake & 1.50" exhaust & do a direct head swap comparision?
That way you might be able to see @ least what a 1/2 point increase in compression can or cannot make more/less torque?
Also to see if it is a restriction w/stock size valve running a 194 cyl head.
I did mention to Tom to mill the head (the 194 head) more to bump it up even more than 1/2 point.
Just a thought.
