KB Dome Pistons in 383. Do you like them?

Actually lived quite well until we swapped the single plane intake for the dual plane (both vintage Edelbrock pieces). He was autocrossing the car and I could see from the side lines that he coming out of the corners MUCH harder with a great increase in low end torque. That was the first spun rod bearing.
What if any oiling system mods or improvements had been made? One of the main reasons external line oil systems were engineered was to improve availability of oil to the pickup during high G forces. Not saying it would take a dual line system to live, but a 1/2 inch pickup and a pan with good baffling would probably help.
