Edelbrock Performer Intake Routing
I changed my plugs/did a compression test on the engine tonight (It was cold, but there was no way I could have done this with hot headers in the way) here are the readings: 1:180 2:181 3:190 4:175 5:179 6:172 7:172 8:181 What caught my attention though was that the plugs on the passenger side had carbon deposits and looked like that side is running rich. With this double plane intake, is the passenger side of the carb feeding the passenger side of the engine or do the channels cross somehow?

They do cross over, these intakes are sometimes called "cross-H" intakes for this reason. The "planes" in the intake are arranged so that adjacently firing cylinders aren't fed from the same side of the intake. 1 4 6 7 are fed from one side and 8 3 5 2 from the other side.

I have seen in the past where people have got a different jet in each corner to correct situations like that. But if I remember right it's usually a holley carb that the do it with and use an Air Fuel guage or exhaust temps to set it up. But the carb experts need to chime in now and correct me if I'm wrong.

performer intakes have bad problem with fuel distribution because 4 of the intake runners are exposed to the hot tappet chamber oil. a good heat shield under the intake will help. been there done that :chevy
