Can you please post up some pics of this rare head, I really like the super deep tub chambers they are like some of the Harley aftermarket head combustion chambers focusing the charge in the centre of the piston with little wasted on the bore walls of the engine.


I will see what I can do... which translates into asking Tensandtwenties to do it for me since I am just barely computer literate.


I'll post up some this weekend. Probably in a "for sale" ad.

needs very high RPM?
How would it work on a 1608 engine? Or an A15?


Personally, I think it would work fine on any engine that you can routinely drive in the 4500-9000rpm range. It doesn't do so well below 3500, hence why he says "worthless for a street engine".

Anybody want it for their high-revving A-series?

Are those single springs for high revs?
valves dont seem that big for high flow.

As I recall, the head builder felt like bigger valves wouldn't do much to improve flow?

Port inlet is matched to an OEM A14/A15 gasket, not the GX gasket, so...
