BTW, I’ve gapped valves many times, but never on a 617. I read about the bent wrenches, I ordered some from Etsy. Then I get a message saying they’ll ship in 4 or 5 days Almost 2 weeks and I still haven’t got them. I really wanted to go north in this car in the trip I’m now on and I figured it was time to admit that I still didn’t know enough about this engine to get that damn shaking out. And I read about valve damage from heat when they wouldn’t close completely. Turns out they were getting close to that stage but not quite.
