Is the 999cc spi head and the 1108/1242cc heads the same???

assume you mean 899 and no

think he ment the 999cc uno fire engine.

Should fit, but not sure if the valve size will be exactly the same ?

I've got an 1108 head for my 999 engine, the inlet ports are smaller on the 999 for sure. I'd read that the valves were smaller too but they look the same on my two heads.

I've read somewhere that all the small fire engines up to 1108/1242 spi share the same head, just wondered if anyone knew for sure.. Does anyone know the valve sizes for the 1108/1242 head???
