Isambard, if you follow this link, there's a .pdf attached in the first post that includes 4.6iS timing parts.

I copied a potion of the parts of that .pdf as you can see below..... since these are for a 4.6iS check here:

...to see what the exact confirmed correct parts for your 4.4i are.

In any case, this should give you a *ballpark* idea of the parts involved.

Hope that at least points you in the right direction. Unsure if any difference, but that's what I replaced for the timing guide refresh. And it's up to you, but if the oil separator system, coolant valley pan, and rear coolant crossover gaskets need refreshing, might as well imho. Valve covers might be ready for a good cleaning, blasting, and powercoat of the top side. It's a slippery slope between "if it's good, leave it be" or "it's overlapping work, might as well" (at least it was for me).

Hope that helps,
