true dat.. but you can make up some bottom end with a tight centerline cam say 106 or 104 deg, and a set of rhoads lifters will also help.. the more the duration more radical it sounds, but you will lose bottom end power.

For those who are looking for just a step above stock, but want to retain the stock torque converter, stock cylinder heads, etc, this cam is the way to go. It's also a great choice for towing, RV use, etc. With a nice broad power band of about 1600-5800 RPM, this cam will give your engine a "slightly rough idle," just enough so people can tell you've "got something under the hood," but it will do it without losing hardly any of the low end response and drivability of a factory high performance cam. Duration at .050" comes in at a nice docile 224 degrees on the intake and 230 on the exhaust, and it's on a 110 degree lobe separation angle. We would NOT recommend this cam for ANY stroker setups, it's going to be way too small. We feel the three bolt timing chain attaching system is far superior to the single bolt, and so we offer this cam to fit only three bolt timing chain sets. We carry them (along with the required bolts, etc.) on our timing chains page. Don't forget to order Comp lifters and break-in lube (shown below) with your new cam! These items are considered essential to ensure that your cam has the longest possible life and is fully covered under Comp's warranty policy. And, since this is Comp we're talking about, you can be assured of two things: The product is 100% made in the USA, and the quality is second to none.
Part No: 145-1223 - Comp Cam Xtreme Energy .477/.480" - Price: $139.95
Found this one on 440source I thing this is the one that i want. Can anyone that knows more than i do let me know if this will be ok.

As mentioned before bro, e-mail 440 Source and discuss what your engine is, what it's in, what you're using it for and they should be more than happy to point you in the right direction and what to look out for. Let us know, ok.

What is the difference between the 360 and 361 is the 360 a small block. If not would these heads have a better compression? http://phoenix.craigslist.org/nph/pts/1045760523.html

Check out a site like Amazon and get a book on Mopar big block motors. You ask anyone on here and I can pretty much guarantee you they have more notes, books, magazines, downloads, piles of paper than you would believe. A little reading before hand WILL save you money in the long run. Books are cheap, engines aren't. Just trying to help bro.

As I said in the pm, those are motor home heads, looking at the casting numbers to see what type, I believe the last three numbers are what most people use to identify them. I would be much more helpful if I was at home as the engine book I have I believe breaks down the different heads.
Do take them to a machine shop as they have a lot of stuff sitting around, I will be selling my extra parts to one when I get back home in a week or so, he said he wants the parts just in case someone comes in and needs it. Also the machine shop will tell you how much it will cost and you may be able to get a replacement for cheaper, but theres only one way to find out.

I also found this, "Motorhome/truck heads with extra cooling passages for spark plug area"
I found a few places sell the relatively cleaned up heads for $99.95 each, probably need new valves and stuff.

HARDENED VALVE SEATS?
I went by the machine shop just down the street from my shop and asked them about my head that i screwed up. and they said it was not that bad that they normally grid that down and put a "perfect circle seal" on instead of the umbrella seals that came off, They also recommended do to the year of the heads that i should put hardened seats in the exhaust. SO, my question is that a good idea or is that just another sum of money to spend?

I assumed that's what you are looking for as the Craigslist ad was for 440 heads.
However Polaradude found that number associates with 340 heads, so if it is a 440 head look for the numbers I posted.
