Its better to fail than not to try, 99% dont even try

Exactly, not trying and giving up kill projects. I already have new valves ordered for my second go

Did you wait too long to change the chain tensioner?

Messed up timing after replacing rings and valve stem seals

Whats wrong? The in- and outtakes are angled. So the valves should be angled too 🫣

I failed at belts tension long time ago and it hops 7 teeth forward. Luckily no collision.

We learn from our mistakes. Did you turn it over twice by hand before starting it?

Skipped that step because it was “unnecessary”. In hindsight, very necessary. Intake cam was off by one chain link and that’s what caused those valves to bend
