Noticed the O2 sensors and wanted to pass on that when they are that close to the open atmosphere, they will give false numbers. Not a huge thing, but might cause you some grief later on. About 18" is a good distance. Hope you guys get rewarded with some good numbers and an engine that will live as well.

Yes, they are worthless without extensions at low rpm. Work fine when we were cranking on it.
