Anyone have any comments on how good/bad these heads are the price looks to good to be true but i haven't heard any complaints/compliments about them.  

Hi,i purchased a set of stealth heads here in australia,had a good look at them in there assembled state,they look pretty good,im a mechanic/engine assembler and think that a a few hours of port and bowl blending,and detail the guide bosses they can be tuned into a really awsome set of street heads,im going to flow mine after xmas before and after the above mentioned work, including a nice valve job and i will post the results..Hope this helps but yeh there worth the money for sure...  

I had planned to get on the board this morning and ask the exact same question.  One additional question.  I am wondering if I can use the stock push rods and stamped rockers with these heads.  I noticed the deck is thicker by the advertisement and wondered if I needed to use a longer set of push rods or rocker setup.  What do you think?

Seems like at least a couple of us are thinking the same thing here with a nice christmas present!  I'll be watching this thread with a keen eye for sure.  It would be nice to pick up a set of these at this price versus the 'brock ones at quite a bit more.  

I beleive the heads you are referring to are a copy of the Edelbrock Performer heads. I've heard nothing but good reports about them.  

The 440Source heads look like stock heads on the outside but the combustion chambers are closed like a 915 head.  The ports are very similiar to the Edelbrock RPM Performer ports but the spark plugs in the Stealth heads are straight rather than on an angle.

You can get the Stealth heads CNC ported by Jeff at Modern Cylinder Head.  They flow 320+ after Modern gets done with them which is good enough for 650+ hp.  

If you guys bug Randy enough I'll put a set of the Stealth CNC heads on my 505 and do a magazine article.  I don't really need to do this since I know they will make basically identical power to the CNC ported Mopar 452 heads that I just ran on the 505 motor (680 hp) but sometimes people want to see it for themselves.
