Oh! Sorry, I'm a boring ol' Ryu.
I usually avoid giving advice because I never feel like I'm qualified to. But here are some things I can point out for you since I use to main Ryu and now main Evil Ryu who has a pretty similar gameplan in this match up
Gonna have to rewrite this. For some reason I was watching PR Rog's stream and wrote up stuff about Rog instead of Honda.
-You have a fireball so you control the match up. Throw them from safe distances and force him to approach you and anti-air accordingly. You have to know the ranges though as they might empty jump. SRK when they're closer and far HK from further away.
-EX headbutt is now a easy punish since it has almost no push back. If you block it, make him pay for it. Hit the lab and find out what your best punish it and remember to use that.
-If you knock Honda down his wake up is pretty weak now. His EX headbutt is easy to safe jump without needing super strict timing. Try to exploit this aspect of his game. If he's just willing to block, maybe you can start sneaking in cross up tatsu or overheads to get a little bit of damage.
-I think cr. HP might be a good button to use against Honda's who spam butt slam. I know Evil Ryu, Akuma, and Oni's version is great against it, not sure about Ryu/Ken though.
Hopefully that helps a little. I'm not too great at that match up either. Lame Honda's can drive my patience even if I have the lead lol.
