So I have a set of used B1-BS heads that I'm going to run. They've been sitting on the shelf for a few years so I'll be taking them to a local performance engine builder to have them checked out.

Since they're going to be apart and on the bench I thought I'd ask the experienced head porters here if there are any known problem areas that I should (or have my engine builder) clean up, smooth out, port or whatever the case may be. Also, flip side are there spots that I should be sure to leave alone. I'll be leaving the ports alone, they're gasket matched already.

Thanks in advance for any advice, I'm looking forward to getting the old hotrod back on the road.
