Hi, Al....I have been using NGK BR9EQ plugs.
Then I tried some NGK B9EGV plugs, and I could not screw them all the way into
my engine with my Craftsman deep socket, because the length of the plug left
sticking out of the engine was still recessed partway into the spark plug hole,
and the socket kept slipping off the hex portion of the plug, which would not
allow me to tighten the plugs. Both plugs are identical in length below
the sealing washer....it's just that the height sticking out of the engine is
shorter on the B9EGV plugs than it is on the BR9EQ plugs. I went to
AutoZone, and they substituted an Autolite 2526 plug for the BR9EQ, and it
measures the same as the BR9EQ plug, and I could install it with a standard deep
socket. Unfortunately, I don't know what the R or the EQ stands
for....just know they are much easier to install. Perhaps someone can shed
a little more light on this subject. Thanks. Paul

What are the make and number of the unshrouded
plugs??
TIA,

I’m using NGK B9EGV for both leading and trailing;
recommended to me by Paul Yaw a few years ago.
Ed; just guessing, but I think that Paul Yaw link you
referenced is from about 1999.
There
were a couple of times during the dyno runs that the engine got very flooded,
but then started easily when we got the conditions
corrected.
