Current rods are 6.950
To me it looks like the 6.800 rod has the smallest mark and closest to the center.
yes, number 3 intake is the narrowest.
clean off intake valves.
put the 6.750 in number 1 intake
put the 6.850 in number 3 intake.
do it again with those and we will decide.
the additional duration on the exhaust lobe is messing up the comparrison so my apologies for that but the good thing as i mentioned is that one of the rods you have will work and so far number 3 intake is the winner.
the photos are xlnt and can be enlarged.
number 1 intake is slightly closer to the center than number 3 intake but that is irrelevant . I was just curious to see if you could tell.
