I feel like a bunney for asking this question, but should one re seat the valves when de- coking the head?
Why would anyone want to use something that big and bulky for a precision job that only take 10 seconds to do by hand? Just get a regular old valve lapping tool with a suction cup for $5 from any auto parts store. That crank job is WAY overkill. I find it hard to believe it even exists.Scottie
