I know people running 30+psi and really have no issues with heat.. it should sit at 82*c all day long, especially with a Lucas, you'll never get enough fuel in to overcome the cooling system. Sounds like you've got a blocked or jammed thermostat... Also check your radiator for if it's got half its fins missing... They usually are after a few years!
