4 cylinder volvo 1983 any good?

We had an AQ125 in my dads boat and the motor was great. We had an issue with it over heating and after checking everthing we figured that maybe the head was warped. If I remember correctly you have to be very very careful resurfacing the head as there is already very little clearence for the valves from the factory. When they checked mine it was good to go so we did not have to resurface. If you buy the boat if it has the same cooling system I know it inside and out.
