I too had the Weber big bore throttle body and sewer pipe on my 83 GTI.

The most significant modification I made was installing the Weber "Big Throat" throttle body. It transformed the engine, sort of like tuning a turbo today. It moved all the action down to the low rpm range so the car would scream. If you were at stop sign taking a right and hit the gas you could barely hold on to the steering wheel (it was manual) due to the massive torque steer.
How much did u port the head(or hav it ported) cuz i can still see all the cast marks in ur pics.They do look nice and uniform.
