Hi all, new to the forum here. I’m currently rebuilding my fa20 and somehow I got the valve shins mixed up, I’ve been trying to figure out the best way to set valve lash/measure valve lash/ finding which shims go where but I’ve had no luck finding how to do all of that. It’s pretty stressful, should I send it in to a shop and pay someone to measure valve lash or should I attempt to do this alone? Any help would be amazing guys thank you.
