Rocky,

I'll tell you what I think, FWIW. Because of cooling problems that 
many old IH's have, I'd bore the engine the minimum amount. Because 
of the nature of these engines, I don't think you'd gain that much 
advantage anyway.

And that's what I think. When guys tell you to bore it way out 
because they did, or they knew someone who did, ask them how that 
engine does in the desert in 120 degree heat pulling a 20 % grade at 
5mph.
