Ron, Your spot on with your observation, it is different to the Sharp chamber, the Sharp has the plug in the more normal position, and the curved whopdedo twix the transfer area and piston crown area favoured the exhaust side and protruded further into the piston crown area.
I made the Sharp comparison based on the deeper chamber over the exhaust valve.
And of course this Hanson head is a Pop up.
on that note, Andrew, are these Hanson's going on the one with the mushroom cam system, centrifugal blower and stuff ? How much pop-up you got going on their? They cut for the traditional 7/16" Tattersfield-Baron pop-up?
Is your Father inlaw getting his hands dirty on your quest?
Thanks,
Martin.
