Welcome indeed. If it really is a 164 motor, you won't find any carbs to fit - the 164 was always an injected engine. The 3.0 V6 was only ever fitted with carbs in the early Alfa 6, I think. I think these were downdraught carbs - either Weber or Solex, I'd guess.......
I'm fairly certain that all the other cars in which the 3.0 V6 were fitted - Alfetta GTV6, 75 V6, 90, RZ/SZ and later front-wheel drive cars were all injected motors.
Sorry if this isn't much help......
