That's great to know!!! If you say that you would better go for the thickest (2.2) ones I believe you, but I was wondering why the store shows the least thick (1.5) as the one for "repair" and is also the one that is most expensive (*like three to four times as expensive)...
About the hydraulic lifters that can be replaced, I remember a few months back when I was rebuilding my engine I removed four of them, and a little ring that goes almost on top of the lifter broke after removed. That made me think the hydraulic lifters couldn't be reused. Maybe I was removing them with gorilla force or not the right way

Or should I be very careful? I really don't need to remove them, but just in case I insert the wrong shims and still have noise and I would like to try other thickness.
Thank you very much for replying
