I had a few of the tubes slide right out and some would wiggle but not easily come out. A small angled pry bar wanted to bend them and not remove them.
So, I grabbed a phillips head screw driver with a shaft diameter just a bit larger than the tube I.D. and gently tapped it in to a stuck tube until it was wedged in. I was then able to just unscrew them out of the holes but turning the screw driver handle.

I got the manifolds reinstalled last night and hope to get some time to work on putting it back together today or tomorrow and a quick test drive before swapping the HEI in with the help if Shifty's thread.

You guys have bene very helpful, thanks!
