That's all good stuff there. I would absolutely have the balance job checked. They are never as close as I like them.
The other thing is that is a bit low on compression. Rather than deck the heads, do all the measurements and then stick the piston out of the hole a bit. That is standard operating procedure, but has been lost over the years, because all the Chevy guys use a zero deck, but it is wrong for small block chryslers. I run mine .054 out of the deck.
