1974 Plymouth Valiant Scamp - Restoration is a strong word


Does you head have the spark plug tubes? If so, removing the crush washers is correct. If you DO NOT have the tubes, your plugs will need the washers. It's not clear what you were doing, just wanted to make sure you don't have a mismatch between plugs/crush washers/head style.

PM coming your way on your LCA's.
Yes, plug tubes are installed. Thanks for checking!
