Just so you know, it's not univerally accepted that the pressure fed tensioners are necessarily "better." Not only do they sometimes fail too, but the external oil lines and fittings that feed them have also been known to leak or fail, which can cause a fire. I'm not necessarily suggesting you go back to non-pressure-fed tensioner, but be aware that there are pros who build engines without them and swear by it. I think that the statistics for longevity of the latest and greatest non-pressure-fed tensioners are pretty impressive. It used to be that people would add an aftermarket collar to the tensioner plunger to prevent total collapse (but would allow an impending failure to be detectable by ear). This might be an option for you too. If I had a very original early 930, I would absolutely go back to the non-pressure-fed tensioners to preserve the originality of the appearance, and to avoid having to slice and dice the sheet metal pan behind the engine to accommodate the tensioner oil lines.
