Default 103 Build

My builder is ready to bolt my 103 , now 107 twin cam, into my bike tomorrow , finish assembly , break in the rings , he says is crucial it's done correctly ,
and then dyno tune it. Had my crank trued and welded ,and new rod bearings,new main shaft bearings , had over .005 run out and he won't build them with that much. Also there was some scoring in my oil pump , 34K , and my cam plate so I went with the S&S plate and pump. He also CC's the heads, bored my cylinders , not sure what pistons they are but they look to have coated skirts , check my piston oilier jets , bigger throttle body and injectors , S&S lifters and push rods , Max-Cell T945A cams , last one of these he did was 112HP and 130TQ . I'm getting anxious now. He's 3 hours from here , sent me some progress photo's though . Pretty happy with this guy , does good work.

So what CC were the heads? Did he shave them to equalize?

Been a while since I had a KB piston in hand, but that'd be my first guess. Unless he coated the skirts himself on another brand.

I'd have to ask him about the piston's , he CC's them to make them even , don't how many CC's they were , again I'd have to ask him .

Edit : Just talked with him , there CP Carrillo performance pistons , he sends them out to be coated.

Made by JIMS V-TWIN performance , guess they make a great M8 cam that performs well AND sounds good . My builder has had good results with them , used to use the T-man 590 for this same build.

I hate being the one that has to ask the dumb question. So is it a 103 or 107? Kinda confused/confusing
