The car has a 2200 stall in it now. The car would not idle beloww 1000 rpm, even in park. We checked float levels, vacuum, several timing settings, different springs in the distributer, etc.
I tore the intake off tonight and couldn't believe what I found. The runners in the intake are 1/4 inch shorter than the openings on the heads. Basically, the very top outside edge of the intake runner's flange lines up with the opening of the heads. No wonder they all leaked so bad. I think the heads are 180 cc runners will the intake runners are 165cc. This explains why squirting WD 40 didn't show up the problem, but 40 weight oil did.
Needless to say, I'll be on the phone to the builder, dart heads and edlebrock manifolds tomorrow !!!
Thanks for the help !!!

Did Barrett say anything about needing a higher stall converter? Is yours stock?
That cam is a little large for a stock torque converter. Will it idle below 1000 rpm in Park?
I would also say you don't need anywhere near a #63 primary jet. Have you checked the float levels? The fuel pressure shouldn't be 8 psi as that's pretty much the limit that the Holley needle and seats can handle without flooding; 7 psi is fine.
I'd run at least 12-14 degrees of initial advance. Make sure the idle mixture screws are adjusted correctly, floats adjust correctly, and the idle speed is low enough that you're on the idle circuit. This cam should definitely idle at 750-800 rpm or so in Park or neutral.
