440 source heads on a stock 440

Its actually going in a 1966 Belvedere 4 door and probably wont see a lot of performance use. I will probably just get rid of that cam and go with one of the smaller RV style cams. I know that the Mopar performance 430 lift cams made a ton of low end in motors with low compression so I might hunt one of those down. Do you think in such a low performance package that there is any advantage at all with the stealth heads or should I just dig out an old set of 906's and have them reworked?

Though it seems to be against popular opinion, I would say there is no advantage to those heads in your situation, other than they are new. That's the thing that almost swayed me into buying those heads - the idea of sinking money into 45 year old open chamber iron heads to 'fix them up' or somehow optimize them was not very appealing. It's a tough pill to swallow when you have the Stealth heads staring you in the face for just over a grand. But, I resisted.

A cam with less duration will be a better choice. 236 @ .050" is not huge but it's not small either. 299 degrees of total duration is way more than needed.

Again, the one thing above all else that would make the biggest difference here is pistons, not heads. If you had the compression to take advantage of good flowing heads and were planning on making some power, then yeah, go for it. To me, it sounds like a cruiser with a little more oomph, like a police interceptor type thing.
