Cam for torque question

If it stinks it due to the tune,plane and simple, it ain't the cam by itself.

I couldn't get any sense out of your timing spec, other than it seems all messed up to me.
The #1 thing is to stop trying to use the Vcan on manifold vacuum; this is nonsense on this size of cam.Go back to the drawing board.
Assuming the cam timing is close, and that there is nothing wrong with your carb, that the ignition system is up to snuff,and that you have fixed your noisy valve train;
Disconnect the vcan and plug the carb-port. Then set the idle-timing to 18*max. Then reset your curb-idle screw to about 750rpm. Then get your T-port sync worked out.(see link below). Once the sync is set, you can limit your power-timing to 36*max. After all this is done, You have to prove that there are no vacuum leaks anywhere,namely; external,internal and including any devices operating off manifold vacuum,Such as the power-valve system. And now begins the fuel tuning.And the rate of advance tuning.
Then, after all that is done, THEN you can hook that Vcan back up to PORTED vacuum,and adjust it's rate of advance.
By this point, the vacuum disparity between in/out of gear should be, with a 2200TC,very minimal.The exhaust should be dripping water during warm-up (off choke). And when fully warmed up and idling, you should be able to hold a rag in the exhaust stream, and afterwards hardly smell any exhaust on it at all.If not, sit down and figure out where you messed up. There are at least four different kinds of stink that can come out that pipe; raw gas,NOx,burnt oil, and normal.Each is distinctly different.
But you gotta get to the bottom of the noisy valve train first! It's gotta be the set-up, the adjustment, or the lobes are going away! Option 4 is as rumblefish says, and I cannot comment as to that.
As to the set-up, well, there are a few things to look for. Obviously valve lash is #1. #2 would be rocker-arm orientation. #3 would be pushrods rubbing in the tunnels, and #4 is geometry. and #5 is crummy springs or crummy spring pressure. So pop the covers and sort it out.

I had a very similar cam in my 360; 223/230/110 with lift of .538/.549 and the advertised was 270/276. It was a zero deck,10.9Scr. I had three different carbs , and two different intake manifolds on it, and after the tune, not a one of them stinked other than normal. That cam made the most torque of any of the three that have been in that engine. It really sucked when it dropped three lobes immediately after an oil-change. I remember it fondly. The cam was dead quiet and went willingly to over 7200rpm.Admittedly it quit pulling a lot sooner,but I just like to hear those dual 3"pipes screaming.
I wish you every success in your search
