Im trying to decide which gap to go with for the rings. Im thinking .22 (Top) .22 (Bottom) or .22 (Top) .24 (Bottom).

The engine is a fully built (Wiseco over Manley), Precision 6765, E-85, Yada yada at 35+ psi.

You think think one of these gaps would be fine or do you have any other suggestions?
 
all your ring gaps atr too large .22 or two hundred twenty thoudsands that is almost a quater inch.

or did you mean .022?

in the piston or ring box there should have been an info sheet, to tell you how to figure your ring end gap.

looking at a Wiseco info sheet...
under "Ring Gap Instructions" it says

Multiply your inch bore size by the "Bore x"column for your application to determine the end gap.

I would use the factor for "Street_ Moderate Turbo/Nitrous top ring .0050 2nd ring .0055

and in notes it says #2 "The gap on the second ring should always be larger than the top ring end gap, this will help reduce top ring flutter or lifting"

EF huttin has spoken:D Listen to him the man know his stuff:thumb:
 
For your goals I would say .022 top ring and .025 middle. I think the street moderate ring end gap is a little tight for your goals. Better loose on the ring end gap. Oil burning doesn't become an issue with our bore size until you get into the .035 end gap.
