First look at the Stealth heads

[Skunkworks Challenger]

Here are some pictures of my 440 with painted Stealth heads.  They are very close in appearance to stock when painted.  They looked great out of the box.  I had mine gasket matched and the valve seats slightly under cut, otherwise they are "out of the box".  The engine has yet to be fired up.  PK

Very nice. You'll be happy with those heads. They flow nicely!!

When I built my 451, I had the valve retainers and springs replaced on the Stealths.  The engine was broken in and then did 5 pulls on the dyno.  No issues so far.

Yup, between 610 & 615 HP on the dyno at 5400 rpm. I have yet to take a trip down the track. I'll get one run and then they'll require a roll cage. From what Kurt told me (Kurt from Magnum Machine that built the motor for me) is that if I put slicks on and hook up good, I'll most likely break the 8 3/4" rear end. It's got 651 ft/lbs of torque which is more than his 9 second 1/4 mile race car. He should know. He builds them and races them. So I'm a little leery to do so until I get a good Dana 60 up under it. Which at my rate may be years from now. Money's pretty thin right now and I've got a daughter starting college next year!! OUCH!!! But I know it's STUPID FAST as it's scared that crap out of me already & faster than anything I've ever had before!! Woo-Hoo!

Broken 8 -3/4 rear end?  Take a look at the case on my 8 3/4 when I bought it.  The case was punctured in three places and braised up and new gears added.  I patched the case in my restoration process.
