Update,
Made large sheet metal dome under each carb to direct the fuel and reduce volume. Pretty sweet job, if I don't say so myself. Took a great deal of volume out of the intake, and keeps the fuel from puddling directly under the carb in a large dead area.

No change! Still bucks and kicks as it always has.

SO I've done the following and noticed no change:
-Played and played and played with carbs, with A/F monitor hooked up. Went Rich / Lean and everyhwere inbetween. IFR changed, IAB changed, Open rear blades more than front, vice versa,.....
-Timing all over the place from locked out low / normal / high. Curve from BTDC to very little...all maxed out to the same 35 degrees or so.
-Changed the intake shape a bit to aid distribution and signal to carb, taking volume out
-Added 4 hole spacers 1" thick
-Increased valve lash about .006"

Nothing has changed the problem yet.
