exhaust port

does anyone know if there is enough meat to grind the exhaust port to a round hole instead of a oval hole??

 

all good was just a thought. might cut one up just to see how much room there is.

 

Would make doing the manifolds a lot easier... I saw a guy on the VH forums do something using a thick piece of aluminium and machine to suit. But that was to adapt a Cayenne V8 turbo manifold to a VH.
