I have a couple sets of the double hump heads and was getting ready to do up some spare engines for next year. Does anyone know if one flows better then the other? This would help in determining which bottom and cam selection I make.

If I remember correctly the 461 flows a little more than the 462 but not by much and the 461x flows a little bit more than the 461's

Thats what I've heard but was also told the 462 has a better plug placement. Not sure what the benifit is. Anyone else?

462 has a different combustion chamber. It has no quench area on plug side like 461 has.
