you'll have to come up with what works for you. The best way to do this is I think to understand blocks are learn about them. A block occurs when your vocal cords lock (open or closed). You cant make a sound because you need for the cords to be near each other so the air vibrates them and thats how sound is produced. Thus, focusing on relaxing a block and creating that vibration is the key. By instinct, a lot of people would just push through their blocks until they got the word out. Their panic would be so great that they would "try very hard" to get the word out and this usually results in a violent battle in your vocal cords. The problem for most stammerers is they unknowingly learn this as a child and it quickly becomes their default habit and is very difficult to undo. You have the advantage of not reinforcing this habit over years and years. I would recommend taking a more relaxed approach. Firstly, the slower you talk, the more time your brain has to communicate with your vocal folds and coordinate. Now im someone who naturally speaks quickly and refuses to sound like a robot for increased fluency, but even I acknowledge that slowing down does help, especially at the start of words or sentences. You can do this by slightly stretching out sounds or words when you talk. For example, if someone asks you which club you support and you want to say Arsenal, you could stretch out the A a little and say Aaarsenal. I find that if I can start off the word smoothly, it helps me continue smoothly. Just keep the initial sound light so that you can build off of it. It's easiest with vowels since you can start soft and then ramp up the sound. More difficult words like ones that begin with hard consonants, such as Bolton or Doncaster, you would want to make the first B or D sound light and then slide into the O which you would be able to stretch out. so something like boOOLTon or doOONCASTer. As i've previously mentioned how airflow between loose vocal folds is needed to produce sound, keeping a steady airflow is very important. If you're blocking and you're not getting any air out, then you obviously cannot make a sound, so focus on having enough air when you speak. Maybe speak in shorter sentences with more pauses for breath. A big indicator for me is how my stomach feels. When my stomach is relaxed and loose, the air flows nicely and I dont tend to block as much. When im tense or anxious, my stomach is tense and my breathing isn't smooth, which makes me more prone to blocks. Also, the smoother I take my breath and exhale, the easier it is for me to speak without blocking. If i'm panicked and I take sharp breathes in and exhale out sharply when I speak, it makes it more difficult to coordinate the sound. Let me know if you have any questions or want anything cleared up.
