Hi there, I had bought a nice alloy second hand cylinder made by maney , it's a 750 but with the 850 head bolts pattern( the bolts holes near the plugs are 1/8" outwards , mainly the rear ones.....????) is that common , or ...........?
lcrken said:I guess I should add that there are several ways to do the 750 to 850 head conversion. I like this one because there is no welding involved. I copied this technique from Steve Maney. It's how he converts heads for the wider bolt pattern for the 1007 cc engines. It sounds like Jim Comstock (comnoz) was using a similar techinique back in his racing days.

I'd forgotten how ugly the standard heads were. Thanks for that.
