what makes you sure it's the gasket? burnt valves give gasket-like
compression symptoms, but no leakage into the coolant. cracked
heads/blocks give gasket-like symptoms, so much so that they're
indistinguishable without detailed crack detection.

there comes a point where it's uneconomic to repair the motor -
especially when you can buy a low mileage used motor from japan for a
relatively modest sum.
