I think I will just take baby steps on motor size. I know my carb will handle the 1641 and no extra head work is needed. I am only looking for 5 to 10 extra horsepower and believe I can get that out of the 1641. I say that with the thinking mine is down some from the wear. Ga. a little far to travel for me, but might make a good midwinter roadtrip!!
Okay,
