In my opinion I have got more likely a valve problem, the smoke appear for a while on acc and then disappear
now the problem is which head need to be serviced... :?:
Since the problem seems to appear on hard acceleration I would guess that you have worn intake valve guides and bad valve guide seals. The giant suction created by those big pistons will pull oil down a marginal guide in a hurry.

Having done both I would say that pulling both heads is a piece of cake compared to swapping engines.

This is a good question.depends on your pocket.On an 80000 km engine you can proceed in two ways:
1)Dismantle and refurbish both two heads:guides,seals and machining and new gaskets.(and check/eventually refurbish rings and pistons )
2)otherwise cheap repair:without service the other head,,changing only the valve seals or eventually one or two guides involved.in this case is in my opinion a no sense change the head gaskets.
All the other ways to proceed (little less than 1),little more than 2))are in a medium terme economically ‎disadvantageous

I agree with Jim, but as others keep saying do a compression test first would be my advice too,

Fulvio il cilindro posteriore sembra ok, non mi sembra il caso di aprirlo se è a posto

New head gaskets every time they are disturbed for me.

The Honda gaskets are coated with a sealer coating and it breaks up as soon asyou pull the head off.

You could try a liquid sealer (silicon, hematite etc) but you run the risk of clogging an oilway or coolant gallery, which could complete wreck your engine.

Reusing will possibly work but is, I think, a false economy.
It's not falling off, it's an upgrade opportunity.
