I clicked on Mark's link and was reading this material just for the pleasure of reading it again . . . and came across this familiar paragraph: "If you get the impression that a GOOD valve job is time consuming, you're absolutely right! I've got 18 hours in the guide and seat work, and that's not counting cc'ing the chambers. That's why I seriously doubt that you can pay ANYBODY enough money to do this job correctly, so you pretty much have to do it yourself. And you may PAY for a "performance valve job" but I'd sincerely question whether or not you'll actually get one! The problem is that when somebody brings in a head for a valve job, the mechanic immediately knows that you don't have what it takes to do it yourself, and after it's put back together, you can't tell what's been done!"
This observation explains in succinct terms just why we need to do this kind of work ourselves. Even if we could find someone trustworthy, they would in no way take such pains to do the kind of job this document explains so well. For those dark nights and bad weather flights it's reassuring to know just how well the work was done. At least in my case (where I had no previous experience doing this kind of work) the learning experience was great fun. It's fun in fact just reading it over today, all these years later. Here's a link to some shots of my own project for anyone's interest. https://tinyurl.com/3zkjvps3 Mike StirewaltKSEE
