G'day Bushy,
I think a lot of mower people go under ground in winter as the grass isn't growing.

Your HC head looks great, I normally just remove all the carbon, make sure I have a good mating surface and they run fine, I have cleaned them up before better than that, never done one as nice as yours above.

To clean your alloy head, look at this thread for a start.

You can look at more threads on cleaning on this site.
I normally google what I'm after and click on the outdoorking link, I find this easier than using the search option here.

For your petrol cap, you would have to use foam that wont be affected by fuel.
Try to get a another cap at the tip shop or mower shop.
Leave the foam out, if you don't over fill your long range fuel tank, fuel wont slosh out of the cap.

To answer one of your questions above, I have put a normal muffler on a HC engine and it starts and runs fine, that's if you cant get one.

Please keep sharing your images and experience.
Enjoy
