thick gasket, UR manifold and GT30 it

These are not the cheapest of engines to tune. The biggest gains are to be had by fitting a ported big valve head and shrick cam (175bhp), but this will cost you over £1000. Would be cheaper to do as I did and fit the 20V 7A or go the whole way and fit a 20V turbo (if you can find one).
You may be lucky and find a second hand ported head! On its own this will push the engine to 160bhp with plenty of torque.
