I've browsed a bit and found the rules of the European Classic Series: Rules
2.2. Engine
o For the engine, particularities as per the mass-produced motorcycles need to be retained: such as number of cylinders, number of gear ratios, number of camshaft etc.
o The engine sump housing has to comply with the original. However internal modifications are allowed.
o The crankshaft stroke is free. The cylinder bore is free.
o The preparation of the cylinder head is free as long as the camshaft and valve numbers remain the same as the original. However, the cylinder head must correspond to the engine?s original model.
Means, using kind of such a modified head in this series would bear the risk being disqualified. Hard to imagine, that someone who is seriously involved in such a racing series would hazard the consequences for this ?
For racing series, where the regulations allow more freedom, such a cylinder head could of course be of interest.
