Dave,
Standard practise would be to do a few basic diagnostic checks. You should carry out a compression check to note any patterns in low cylinder pressures. It could be valve trouble and again, could be a blown head gasket, between cylinders. The latter can give all sorts of misleading things, like backfiring through the carb, etc. It is not necessarily going to leak water, depends where it may be blown.
Don't forget when you do the comp. check, remove all plugs and hold throttle open while turning the engine over.
