Good news. When we pulled the heads, we discovered that the ports had already been gasket matched. It just cost me $25 to have the valve springs swapped.
I think I found a use for my savings. Research and what I've seen on Horse Power on Power Block led me to look at rockers. I think I'll switch the stamped steel rockers for some aluminum roller rockers. I am looking at the following I found on Summit.
