Just a simple question I hope. Does the A112 903cc and A112 1050cc engines use the same head? I found a A112 Abarth 70hp engine but it is missing the head. Finding heads from 903cc is no problem, but I don;t know if the Abarth head had bigger valves or any other dieferences.
I will get a head from a 903 engine and port-polish it. Can anyone tell me the correct valve size in order to use one 40DCOE carb???
Thanks for the help
