Well guys I need your advice;

This is my first and last 426 Hemi engine build, I don't know if I am getting paranoid in my old age but I want this to be perfect. I have talked to the local guys, I have spoken to the Hemi specific machine shops.
The local guys have all the right answers without listening to what I want.
The Hemi specific guys want to the complete build as well as the machine work.
I would like to have the machine work done, then put my 426 back together myself , not because I would do a better job I just love doing the build.
It will be a stock engine going in a 67 Hemi GTX, the only differences will be a slightly larger hydraulic flat tappet cam, various other upgrades and a six pack.
Any advice would be greatly appreciated.

Thanks Bob, one old dude
