No Stealth heads... You have to replace everything except the valves to make a good head, you have to clearance the pushrods, and then they are still not helicoiled... Go with Mopar or Edelbrock, and I would say no to Edelbrock if you were talking smallblock. I think the best intake for your build would be an Edelbrock RPM.
Do not go cheap on the pistons, get better, lighter pistons and balance your rotating assembly, and ignore any claims of what compression that any ad claims with different CC heads... Do the math... 440 deck hieght is 10.72", and the stock rods are 6.768" and most aftermarkets are 6.760", the stroke is 3.75" and the compression hieght of your piston is ???
The last 440 that I built using Diamond forged pistons with the low expansion 4032 material had .012" deck clearance and an additional .039" with the gasket to end up with .051" quench. On a 4.35" bore, zero deck could equal hitting your heads with your pistons, especially with the added clearance of a 2618 forged piston.
I think the Icon KB237 (USA made) forged 2618 piston comes out to .010" below without having to deck the block, and is what I am using on my upcoming 440 build.
I am not fond of the clatter of the Xtreme Energy Comp cams, so off hand, without digging I would say a .474 or .484 Purpleshaft makes a nice old school cam, and Lunati has some good looking specs on some of theirs as well.
Need to know your final decision on 3.55s or 3.91s and tire hieght before you pick a cam and converter.
You can get into the 13s with 3.55s and not run the hell out of your engine to go down the highway.
The 3.91s and a bigger cam will get you deeper into the 13s, but 12s or lower I think is reaching without spending a lot more money as your car is likely around 4,500 pounds curb weight without a driver.
I will be building a 440 for a '69 Charger R/T in the next month or 2, and I can take some pictures and share some specs if some of you have an interest. After the 440 and a 360, I hope to get the block and rotating assembly back for an Indy 493 that should excede 700hp and will be going into a '67 New Yorker later this year, so until then I can't tell you honestly how well it will do in such a heavy car.
As far as headers go, the Hedmans that they claim to fit, really don't, someone else here had experience with the C-body Hookers, and said they had to do some bending for clearance, so my bet would be on the TTI headers... ($$$)
