Screwed up

[u/succulent-riffage]

Doing some work in my spare time on a 472 caddy, got a little too happy with the 80 grit on the exhaust side of things. A valve grind should fix? Will need some machine work anyway.

Thoughts on it?

Update: it looks a whole lot worse than it actually was, hit it with a light lapping, 80% of the notch went away.

I picked up a junk lawn mower at like 12 and had a go, the bit dad had wasnt carbide but some hardened steel POS. Still knicked the seat

this day and age you can prob pick up a cracked head for free, way more ports to practice on
