Cleaning Cylinder Head After Valve Lapping

Duratec head is stripped, de-coked and valves are now lapped in. Everything is out apart from the valve guides. I've wiped all the valves/passages down over and over but wondered if there was anymore I can do to make sure everything is clean?

Usually once I have lapped the valves in, and the cylinder head is ready to be re assembled, it goes back in the wash tank and has another thorough scrubbing. I flush the paraffin or cleaning agent through any and all oil ways, through the water jacket, and use small pipe cleaners on the guides and large ones on the ports.

It doesn't take long when you get into the routine and it can't ever hurt!!
