Moto Guzzi Cylinder Head Fins repaired

I am finally going to get on with my Guzzi project that has sat against the dining / living room wall for the past 18 months.
 Most of the actual frame mods etc have been finished for quite a while and I finally started cleaning up the 1100Sport engine that I will using and also filing round the square finning of the barrels and heads. Also had to get a few fins repaired one of which was particularly badly broken. I shall be getting them vapour blasted too for the final touch.
