EGR valve should be enough, its best to go through the two port ported vacuum switch, use ported vacuum not manifold

Got it working now. Adjusted the ignition a little higher, and adjusted the carb to richer blending. still running without vacuum to the distributor. Butt it works fine. Planing to change this to one without duobble vacuum.
No more spark knock.

There is nothing wrong with the dual feed distributor, ported vacuum to the front manifold to the rear, will advance for power when you accelerate, will retard for emissions when you decelerate
