I have the regular pacemakers on mine and I've searched for the source of the ticking noise which only began after the installation of the extractors. I can say for certain its not the lifters, not the injectors and not an exhaust leak and have come to the conclusion that the lack of meat in the walls of the pipes allows combustion noise to travel or something.

That's exactly what it is, the thinner walls don't deaden the sound of the valves.

Whilst the extractors are bloody expensive (compared to some), the HPC coating is pretty cheap...

It normally costs about $200 to have a set of extractors coated, but these are coated for only $145.

According to an article on the development of the EB XR6 in AMC, Ford/Tickford looked at using extractors but the gain was only 3kW so they decided against it. Didn't specify what type of extractors however - and I wouldn't assume that ones available now would be better than what those guys could come up with.
