Flathead oil smoke right exhaust / help

[guy1unico]

Hello
I've been battling a oil smoke blow by on the passenger side exhaust for a good 8 months. It is getting me down.
Here are my motor specs.
Motor rebuilt totally in 2011 no problems until end of 2014.
49 - 53 Ford with 3 3/8" bore and Merc crank
327 chevy distributor
3 carb intake running only 1 .. 48 Stromberg carb in center
Plugs are new Champ D 16
Vacum is steady at 20...checked from the intake
We listed for any air leaks.... with a rubber hose screwed into a plug hole and compressed air the other hose was in the oil inlet where we listened (No air bypass sound)

Compression check
front
L R
100 70
100 110
80 100
110 120

miles since rebuilt in 2011
3,000
Added 1 quart Marvelous Mystery oil to 4 quarts Valv. VR 150 20 w 50

Heavy blue smoke occurs every time I gun the motor in neutral, accelerate from a stop sign or enter the highway. The smoke will go away after the initial acceleration.

Any ideas of what I can do to totally keep my motor from smoking out of the right side exhaust?
left side (driver's seems to be fine).

Thank you,
Guy
