1972 Chrysler Newport with 400 engine. Completely factory original with 80,000 miles on it.
I had a moment of teenage dumbassery when I dropped a screw into the exhaust port for the choke and couldn't find it. A week or two later it started knocking. I've started disassembling the engine, and that screw ended up lodged in one of the valves at the front passenger side of the engine. When I shine a flashlight into the port, I can see the screw head, and a round metal shaving in there. After it was knocking, the car was ran for about 3 blocks home, and I never started it again after that. What kind of damage is possible here?
Also, while I already have everything apart, what parts should be checked for wear? The bottoms of the lifters are slightly pitted from the car sitting for 20+ years, and I plan on replacing them.
