Bit of an alternate view here...I do agree not to pull the head specifically
to install hardened seats. However, my '70 Datsun 2000 roadster did not
have hardened valves, and I Did use Lead Substitute, but the valves pounded
into the cast head anyway, and I had to have the hardened seats put in.
But only do it if you're tearing it down anyway. When I ground-upped my '59
TR3A, and rebuilt the engine, it only made sense to add it to the machine
work I asked for.

the road, I might get to drive the car again in January! Thanking Odin for
