Do I need to re- torque a payen BK450 which looks to be composite?
And do 1380s have habit of going between 2 & 3 even when both surfaces are nice and true ?
( not a lot of meat there )
Thanks in advance Gray

Thanks But the reason why I ask is a mechanic told me as it was not a copper jobbie it’s not necessary?

Yes, after one or two heat cycles do a proper re-torque.
Doing each head nut in turn in the correct sequence, undo the nut half a turn then re-torque to the correct figure.

Thanks a lot . I know there’s a lot of talk about torque! There down at 42 would you consider that correct on a 1380 not that special fast road motor ?

Sorry didn’t answer your question Mechanic not a Mini specialist.
Think that’s the form on modern engines with composite head gaskets ?
