Diy Valve job

My question is: if you already have it in your head you want to do this, then why the hell are you asking for people’s opinions “IF” they think you can?
Just flipping do it. When it goes south then ask for help. If it works- tell your story.
It’s your engine , your money and your time not my decision if YOU can do it or not.

I never ask if I could do this, I ask what I need to do this, what are people using on this site to do their own.
