660 head and cam

in process of rebuilding engine. my wet clutch grenaded trashing the drum and sending a ton of metal shavings thru my oil and ruining bearing.

just discovered today my cam and also where the cam rides in the head and valve cover seem to have taken a beating from this as well. I can buy a new cam but my question is what about the head. the surface no longer looks polished and smooth but looks dull where the metal has wore on it.

can this be re-polished or will i need to get another head and valve cover to go with new cam??

sorry to hear about moter what did your wet clutch do ,because there another one on here that just had his pins come out wiping his wet clutch out also. don't know if you can have your cam journals reworked an line bored or not maybe talk to benchwork to see

Yes pins broke on mine also but it was those cheap replacement shoes that guy in Louisiana was selling. tough lesson learned.

just rebuilt the engine last spring and now doing it again.

damn that shit sucks a big one just bring back better than before what have you done to the moter on frist build I saw on your other tread that you think it got your head cam journals anything else get wiped out

new crank pin and bearing, crank bearing, cylinder, piston, wrist pin, timing chain,

so far thats all i have come across.

all of the above was new after first build.

now i will be bored 40 over and moving up to 10:1 comp. and JBS sheave, all new wet clutch adding weight to wet clutch.

not sure what to do with the cam stock or next step up.

i dont want to go to crazy on head work or biggest cam.

I would check your oil pump good (maybe replace) the cam I would at lest do stage 1

PM sent about used Head assy, And I also have 2 stock 660 Cranks for sale.
