Ring gaps

I’ve got an engine in I’m building for someone

Not much info, looks like forged pistons from acl, which I’ve heard are made by mahle

Any ways I’ve tried to find specs of the ring gaps, but Internet is not my best friend. I know what stock are, just can’t find info on mahle. 0.4 and 0.7 I have sitting rings on block,

TOP COMPRESSION RING
Ductile, Grey Iron & Steel = 0.013 inch

INTERMEDIATE COMPRESSION RING
Grey Iron = 0.013 inch
that's for 86mm piston (3.38inch) moderate performance


RECOMMENDED END-GAP
TOP COMPRESSION RING
Ductile, Grey Iron & Steel 4.000” Bore Example Recommended Min. Gap Factor
Moderate Performance .016 - .018 (.004 per inch of bore diameter)
Drag Racing, Oval Track .018 - .020 (.0045 per inch of bore diameter)
Nitrous Oxide -- Street .020 - .022 (.005 per inch of bore diameter)
Nitrous Oxide -- Drag .028 - .030 (.007 per inch of bore diameter)
Supercharged .024 - .026 (.006 per inch of bore diameter)

That's what I've found for Mahle

I've built few engines wits cp wosnier and je pistons and usually go for 0.5mm top 0.6mm mid
Bigger gap won't hurt it
