I do not believe that the valve seats have been hardened. Should I use a lead additive in the gasoline? | | | | | Joined: Nov 2006 Posts: 2,544 Shop Shark | | Shop Shark Joined: Nov 2006 Posts: 2,544 | | | | | | Joined: Jan 2013 Posts: 31 New Guy | | New Guy Joined: Jan 2013 Posts: 31 | Are hardened valve seats a waste of money? | | | | | Joined: Sep 2001 Posts: 29,262 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,262 |
As Don posted, neither hardened valve seats nor leaded gasoline are needed in a 216/235/261 engine, unless you are regularly running the engine at very high RPM for long periods.
Either would be waste of money.
High-compression, high-octane, muscle car era engines are another matter.
