I finally dug into my misfire on my 96 Ram 5.9 Magnum. As I suspected from leak down testing, I have a burnt exhaust valve on cyl 1. I got the drivers head off yesterday and can visually see. Going to do the intake plenum block off plate as well.

Since I am going to be this deep in, considering a new cam. 93K miles and bottom end is in good shape. I use the truck a lot for towing camper and car trailer, so for me a towing cam would be good. I do have a SCT tune, but will keep the stock intake and heads (assuming they are not wasted). 3.92 gears.

In talking with Comp and Hughes they are saying these cams.

Anyone have feedback in towing use?

Side question, on these engines, when the crank damper is at TDC, should the distributor rotor point exactly at the “Cylinder 1” marking on the plastic inner cover? Mine is slightly before and unsure if this is correct. I do note a tiny bit of timing chain play if I reverse it, but not that much.
