Initial head torque sequence completed, we set the valve clearances, start her to heat up, everything peachy. Then re-torque the head, rectify valve clearances and start. Then a feared tapping noise ……… the valves touching the pistons! After a phone call, Johan advise to increase the valve clearance gaps and this is applied. The engine is quieter with a slight tappet noise.

Is she ready to race? Well that is the question on our minds. Johan has secured a 2mm copper head gasket which might just give us the clearance we need. Time will tell, but it is almost a sure bet that she will make an appearance!
