these are pics of the ports on my 1400 head
the grinder is going at them soon but where do i take the metal out?
as u look into the port the inlet is offset to the valve. and the mixture flows in a corkscrew effect
whats best? keep the twist or open the port out removing the twist? looks like a lot of meat there so i reckon u could take most of it out.
whats the plan of action
(btw im not gonna get a 1200/1300 head yet b4 u suggest that)
