Not imperative but best practice is for the folded flanges around the openings to face upwards (against the head). Reason is simple, if erosion occurs, it normally occurs on the folded flange side and it's easier to resurface a head than to deck a block.

Agreed but as I recall some gaskets are not quite symmetrical and may have holes slightly offset toward one side or end. Make sure yours isn't one of those because then it could only go one way.

Many thanks, makes sense. I check the gasket a place it with the best fit for holes and studs.
I had coolant leaks last time, with a new gasket, which was aluminum clad on both sides. Did not use copper spray then, but will this time. Have checked the head for waves and warps, but it is all within 0,2 mm, less than 0,01 inch. Wish me luck. Cheers Roland

One major reason for having a head gasket failure shortly after replacement is the failure to re-torque the cylinder head after an hour or two of initial running. And you should check it again after perhaps 10 hours and again seasonally until it not longer requires tightening.

Hi Owen
Will definitely do that. Thanks for the advise, the workshop manual is not very specific on this. Will write again and tell if the gasket is tight, hopefully. Best Roland
