Well after reading the thread as Ron advice, actually I read the whole thing and I'm glad that after 8 years away from the hobby, come back and find such nice products is kinda dificult to pick, but after a little of reaserch and talked to Ron I just receive my B5 and can't wait to get it going. And for all the people that are pitching in with test, what work, what doesn't work as well as others (pipes) you guys are very helpful and keeping the thread on the topic, thats a lot to said and I hope to be here soon doing the same. Back to the engine, Looks great, large head, lightweigh. My problem now is what kind of fuel I can use with the same or very close formula to the
Werks 
fuel, I can't find
Werks 
fuel in Western PA, if any body here from this area know, please post it here or pm me.
Thanks to Run for answer all my e-mails, you have a new customer and a other
Werks 
in the track.
Regards
Elvin O.
