It's better by hand isn't it? I've always though turning them both ways gives a better deal.

Although I have read if you've got multi angle seats you shouldn't lap them as it rounds them off into a curve and they don't seal as well.

I have a sucker stick and on something a little less trashed- I would.DodgeRover wrote: ↑Wed Aug 10, 2022 9:45 pm Next you will be telling us you lapped them by hand with one of those sucker sticks not a cordless drill....
The valves had quite severe burn and had hammered a groove into the sealing faces. That would never seal, and truly the valves need to be replaced but hey, this is Cuban Pete. There'll be no such thing here.
So, I ad-hoc'd a lathe by holding my drill on my bench and filing the face back flat again. Long gone is the case hardening.
Then they lapped in. The early LA had a single angle cut.
Look at it this way, the intake valves up front were closed. The rainwater got through.

Cleaned up. I'm going to argue golf ball physics and claim the random surface texture allows high speed air to travel better because of less transitional surface shear.
The others on this side weren't quite so bad.

How much were new valves - when I bought some for my pinto they were only a couple of pounds each

No idea. That's more than a couple pounds a pop I want to spend on this engine.DodgeRover wrote: ↑Fri Aug 12, 2022 10:08 pm How much were new valves - when I bought some for my pinto they were only a couple of pounds each
I decided to get all Heath-Robinson this afternoon and connected the remains of the shed wiring to the small generator. Nice in theory, but modern electronics are all shit and the LED strip lights protested the rather raw output from the generator by all going up in smoke. Still, I managed to get the head cleaned up in prep to lap the valves in.

Re: 1966 Plymouth Fury 3
Got the valves lapped in, and it got a bit late to be running the generator so I packed up and will refit the springs tomorrow.
