So, my options are:
1) Use the 74 head which appears to have larger ports which might give some improvement in performance. But I'll need to replace a few valves/guides. I would send it out but the budget for this is $0 so it will be a learning experience for me.
2) Use the 73 head (including it's matched manifold) and "just" adjust the valves and put it on the 74 block.
Any clue how much of a gain in performance I might get from the later head? I saw the reference to the difference in this post:
