Sand cast cylinder for v4

Hello, I would like to know if anyone would be interested in Vmax 4 1000cc cylinders designed for a 64mm stroke. The cylinders would use Vmax 4 stock heads, but with a larger coolant capacity and a very elaborate racing porting. The price would be $ 4000 for a set of 4. It would be left to engineer the bore and make the nikcil. If you have any interest contact me in PM.
