Good old Google Translate doing it's job nicely there lol!
My Franglais tells me this means "Does anyone have any information about the 12v head so I don't have to abandon it".
Again from my very limited Franglais I think I can make out that he's asking about whether anybody has a solution for the valves lifting >40psi.
Nobody really has any solution - it's not the actual hydraulic lifters that are the problem, they merely show the issue very badly when the valve lifts, as they take up free lash that is only there since the valve has floated. Other than uprated springs, but then you run into issues of snapping rockers as they're often not strong enough, the 12v head also seems to have more issues with cooling than the 8v, which is already bad enough!
Don't run the turbo as hard as 40psi - monitor the exhaust manifold pressures also, they shouldn't exceed 40psi when on non-VTG turbo.
Mon Français est tres, tres mal - pardon!
