Welcome to the Home Page of Doctune's VeeDub
dubZilla cylinder heads

Using brand new Mexican castings we have produced Torque Monster
specification modified cylinder heads to give you that extra grunt when
you need it.

To keep the torque at low rpms we have retained the 29.5mm exhaust
valves, to extend the max power rpm we have fitted 35.5mm inlet valves.
This gives an exhaust valve to inlet ratio of 83% which is ideal for naturally
aspirated street/strip use .

The heads will complement aftermarket tuned exhaust systems and carburettor
conversions. The heads are fully modified, assembled and ready to use.
