Even when raced these engines don't wear out very quickly. You're more likely to have worn clutches and suspension. Check valve-clearances. Valve-stem seals seem to wear out quicker when raced in hot climates.
previous owner said he had valves checked last year, he had put a thinner head gasket on. He said it was smoking and was told it was probably rings.

My gauge has the Schrader valve near the gauge.
