Thanks for the replies...helps me decide what to do.
I drove my truck with this engine in it for quite a few years, but it was a quick swap in...I didn't even notice the humps on the heads. It was a great engine with the 3-speed.
Now, I envision a vintage-looking 331...accessory holes are on the ends of my exhaust manifolds. I guess my toughest choice is whether to put this engine back in the '65, or go with the 400 I just finished.
Then there's the '65 283 out in the barn...

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.
