That so cool...
Well I'm not surprised... It was bound to happen... Someone took the OHV idea from a flat head model A type engine, and applied it to a Briggs setup.. Really cool...

In the same sort of crazyness idea, I think there was a guy on the opposing faction site, where he made a 4valve head(come to think of it, it was a complete billet engine) for a big block clone...

Neat.

Blocks is blocks is blocks... A disk in a tube going up and down. Weld in the old valve pocket, deck and bore the block, and make sure the pushrods line up, and it's done.

I'd like to see a pair of GX340 heads on a Briggs opposed twin.

I see he was using both valves up top...
I've seen one model A conversion head that uses the exhaust valve in the block as normal running off of the cam. The intake is running ohv, using an extra long push rod through the old combustion chamber into the head (minus the intake valve in the block of course).. Running like an ohv engine...
The head chamber and gasket are shaped to block off the passage of gasses toward an early exit via the open space of the intake valve.
The carb is attached to the head, the old intake is blocked off.
Now albeit these motors are very similar, space on the small motor will be at a premium, as there isn't much space between the valves, I could also see this on a briggs aswell.

I could see this and the top as an interesting project, if they can can get that to effectively work(the OP post that is)...
