 From your previous description it sounds like you did it 100% correct. 
Yeah, it's "feel". I think if you analyzed tight vs. loose by feel with 
the feeler guage there's probably .001 - .002 difference in there. 
That's just fine.

 From front, you can figure it out from observation... E's and I's are 
always adjacent, since E's dump into one outlet and I's come in from one 
port.

from front E I I E E I I E E ...

AMC sixes always have "E" as the front-most.


It's not that critical especially in this motor! They shouldn't be so 
loose as to rattle around, make noise, and let parts hammer each other; 
they must have SOME clearance else parts wear with constant contact, 
don't get lubed, and if tight enough, the valve never really closes, 
leaks, and burns. Plus parts get cold (weather) and hot (mtn climbing) 
and expand/contract so the factory just works this crap out and puts it 
in the book!

A valve spec'ed at .012, but set at .014 or .010 will be fine. Maybe you 
could hear .014 with a good ear..

In fact, it's been 6000 miles since I did valve adjust and torque on 
mine, better do it this weekend! Twice a year is easy enough, it all 
takes what, 40 minutes?

Eh, depends on the fan I suppose, but I just make sure there's nothing 
to get sucked into the fan. At least on the 63-earlier Americans, the 
fan is actually hard to reach.
