N62 engine valve stem seals

I sit with a engine doing the smoke screen trick at traffic lights or then crawling in traffic and then accelerating. Feedback from my mech i that the N62 engine - 4.8is is a valve stem seal problem child and it cost a bag full of money. the car done only 110 000 km!

the proposal is to do the following:

1. Take heads off, recon heads, new head gasket, replace valve guides and seals - most expensive option
2. Keep heads on vehicle with compressed air in piston and only do the Valve guides - Cheaper option

Now the question is: which one?
