Couple of things:

1. you “looked” at the block and head, it’s unlikely that just by looking at them, you’d be able to see the problem. Just my experience, unless it’s something catastrophic.
2. how much is your time worth swapping parts around? I would think the better option would be 1-buy the tool(s) to diagose your problem properly or 2-bring it to someone who has the tools to diagnose your problem properly
3. if you choose option 1, then get yourself a leakdown tester
4. the only way you can be absolutely sure you don’t have air pockets or to put a vacuum on the cooling system before filling it.

I use this, but I’m sure there are other more resonably-priced alternatives
