The shim kit for the 1125 isn't anything special, the usual 'stay away from China' applies
I have a full set from EBR and the usual big Hot Cams kit everyone has. The EBR set is nice because it goes to the 0.00
0 That lets me set the valves exactly at the loose end of spec, doing that usually lets the next service adjustment, just be a 'check' and more time for beer
For the last 30 years I have always checked them before installing. It's not a job you want to do twice and I mix in the unlabeled OE ones I remove. I have
never found one out of spec. I'm not saying it's impossible, it's super easy to just check them. I also remember that one thread you're talking about where the guy swore he could 'sand them down easier' LOL. Uh, no. Nothing to see here, move on.
