The fact that number 2 exhaust valve=C2=A0is not the same colour as the oth=

Okay, here's the latest! I finally got to pull my head If you remember, I h=
ad 155 lbs of pressure in cylinders 1, 3, and 4 and only 25 lbs in cylinder=
 number two. So with the head off, I was prepared to find a problem with I =
flipped it over to expose the valves, no such luck. Other than number two e=
xhaust valve being a bit black, no cracks, nothing stuck and it looked fine=
. So then I went to look into the cylinders themselves, walls smooth, flat =
high compression pistons smooth, number three a bit rough on the top, but o=
ther than that and good.=C2=A0=C2=A0=C2=A0So then I went back to the head, =
put the spark plugs back in and filled the combustion chambers with paint t=
hinner to see where it would leak out. Filled each chamber evenly and waite=
d. Twelve hours later, and other than evaporation, no leaks! All chambers s=
till even in their fluid retention.=C2=A0=C2=A0=C2=A0=C2=A0So then I rotate=
d the crank to get all the pistons to an almost even position and put paint=
 thinner in the cylinders at the same depth. No quick leak, not one cylinde=
r faster than the others and all the fluid finally drained out smoothly and=
 evenly in each cylinder.=C2=A0=C2=A0=C2=A0=C2=A0I'm a bit stumped. My next=
 step is taking the head to a guy in town, an old machinist who builds his =
own engines and runs his car at Bonneville in the 300 mph range. He knows w=
hat he's doing and I'm sure he will give me some sage advice and help. Also=
 as a side note, I went over the head with a magnifying glass and can see n=

king with a 100 pound plus difference, something would be obvious.=C2=A0=C2=
=A0=C2=A0=C2=A0I am also going to be taking off the tappet cover on the sid=

a bit perplexed, but I'm not done. I will find something wrong! Here are so=
me photos for you, maybe you can see something I can't.
Here's the head, upside down and you can see the exhaust valve on number tw=
