Have a gauge...haven't used it in 25-30 years...& just put together the fittings today...to take reading from the port on the intake, just below the carb....will take reading tomorrow....I'm not thinking the problem is with the internals....It doesn't smoke out the tailpipe...and nothing coming from the valve cover with the oil cap off....No misses, seems like its firing on all 6.... 52 Carl made a mention of a leak between the intake & the head...which is a good possibility.....I remember several years ago when I replaced the exhaust manifold on the 292, I had to have the intake planed down due to warping.....I snugged up the bolts a tad... so we'll see.....Thanks for the readouts on the gauge....most helpful.....
