300 SE to 300 SE-24?

[jay300se1988]

Does anyone know if it's possible to fit the 24 valve cylinder head to my existing M103 engine block, or am I going to have to find a complete engine?

I'm also wondering whether the exhaust manifold, inlet manifold and fuel distributor assemblies are hugely different between 12 and 24 valve motors?

I'd also be interested if anyone finds the 24 valve engine gutless at low rev's - I never really need to go above 2,500 RPM in everyday driving because the 300 engine is so flexible and might forget the possibility of a 24 valave conversion if it's not as torquey at low rev's.

Thanks in advance!!!
