I have no idea. It usually means "you get what you pay for", but sometimes it means "we have a big name, and it's going to cost you". But as I mentioned before, given the kind of good luck Jeff Lang has had with his O49 torture test, the O49's may very well be worth it. What worries me about them though is they appear to have very little in the way of air passages, according to the photo I posted the other day (below), but it's not the "whole picture", and somebody who has an RM-049 is welcome to send me one to help with that decision. The reply that the seat material was "good quality" but not an exact material didn't do much for my confidence in them, but at least he didn't say "they're plain cast iron". The other day I asked the guy at FAT Performance what material their SS exhaust valves were, and he had no idea. How do we make decisions based on no information? I'd like some real steady-state CHT numbers from people with different heads on aircraft with KR-comparable speeds, preferably from folks who are monitoring all four cylinders, along with OAT and speed along with that. I seem to be one of the few that records this kind of stuff though...but y'all are welcome to prove me wrong on that. Or you could start this weekend. The end result of this compilation would be a more educated group of VW head buyers...
