I have a line on the 74 Spyder that I have been trying to find. However, this one is missing the cylinder head. Has the Spica in box. I've been away from Alfa's for too long. Where does one go for a new head? Or perhaps, anyone know of a shop that sell comlete rebuilt motors? I used to have everything done by Yanos down in L.A., but he seems to be gone. What am I going to pay for a motor? Ballpark?
