OK.. I have had a problem with one plug fouling because of a leaky intake..

Well the weather was nice and I wanted to get it fixed before I had my hernia surgery this Tuesday since I won't be able to lift of lean over the Windsor to fix it for about 4 weeks..

I pulled the intake, pulled the valley pan.. cleaned everything ( noticed the heat crossover was leaking under the valley pan).. and reinstalled everything.

This time I used a thick paper gasket ( about a 1/4 inch) under the carb to keep the holley cooler than just using the thin paper gasket.

Before the fix I had 16 in vaccum at idle now I have 14... I adjusted the idle circuit  to the highest vacuum reading..

WTH? It can't be leaking I cleaned every surface and it looked like new when I installed it...!!!

I put gasket sealer on the paper gasket before I installed the carb to minimize the chance of a  leak...

The car runs much better... it doesn't smell like exhaust under the hood ( which would have been the leaky crossover). Before the fix it would pop once and a while ( I assume oil leaking in one of the cylinders).. now it's smooth sailing..

Should I worry about it that the vacuum reading is less?

Well it seemed to get better when I drove today. I normally get 16 in at 55 mph cruising and it was at that today.. still a little low at idle ( 14 in instead of 16 in)

I know this is a dumb question. . .  Is the vacuum line going to the heater controls in good shape?  How about the brake booster hose?
 
Not too many places it can leak

I thought about that.. the heater vacuum hose is REALLY hard. I had to soften it with heat to get it to go back on. The power brake booster line seems good..

Where can you get a new "tree" or whatever it is called that hooks the vacuum lines to the intake?

You might look at your timing.  If it is late, (I think that direction), the vacuum will be low.  Could explain why it is running better, but carrying less vacuum.
