Coincidences?

I`ve always heard that there was built special 8 valve Harley`s in Sweden way back where they used Rudge 4 valve heads with home turned cylinders.
Hmmm, 8 valve Harley just the tought is a thrill.

Was fortunate at Ekeberg swap meet getting a Rudge 4 valve head to play with.
Didn`t get home until today, have a guess what was my first "to do".

Its just amazing, the Rudge and the Harley IOE from late 24 (JDCA/JDCB) up to 29 J & JD share the exact same dimensions between cylinder / head bolts centers, oh yeah even the same dimensions of bolts.
A plan is getting borned, watch out :-).
