Well here's what I have:

#1     92/95    (jumps to 120 with a little oil)
#2     128
#3     135
#4     135


Clearly a problem with #1 which I assume to be rings given the effect of the
oil. All of the others of course exceed your goal of 120. In your opinion,
would these levels lead to running hot?  What would you do with these #s?

BTW, the plugs were beautiful. Happened to be Autolite 404, any idea if that
is actually the right range?

Thanks for your help,
