I had to cam a little over my compression, but I had to out of necessity after the head was accidentally milled too much. I had to utilize that head, because all the rest needed guides and seats and this head was real nice......BUT it got milled too much. I couldn't afford to whoop up another head, so I had to go with a bigger cam. It worked out well in the end. It took some tuning and I took a lot of your advice and it worked. I learned a lot and I had fun. Even still though, between the two, it runs better on MVA. It IDLES great on either ported OR manifold. It just runs better on manifold. I can't go without giving
@Bewy some credit too. It basically did everything he says. It cleaned the plugs up some and it did pick the mileage up a tic. But the idle quality is really indistinguishable. It MIGHT idle a little better on MVA, but not by much. It does have a stronger vacuum signal, though. Is it a crutch? Maybe and I don't care. It still runs great, so what's the difference really? I know it would likely be "more efficient" with less cam, but I'm glad it turned out like it did. It has gobs of personality. lol
