Here is the link you need for Mahle pistons, see page 17. The 2nd ring gap needs to be larger than the first.

Also, I see that Manley specifies a larger top ring gap (vs 2nd ring). That is contrary to every other source I have seen for piston rings. This may be one of the sources that is continuing to fuel the uncertainty in the engine building world...
