Piston Selection Help Needed

People,
Need a bit of help finding a piston to match my requirements. I need a piston 78mm in bore (78.048mm to be exact - we're going to run 78's with 1.5" "clearance"!) with a pin height of approximately 25mm.
Pin height (also called compression height)is the distance from the centre of the gudgeon pin to the top of the piston, for those who don't understand, or want to know! Gemini pistons come close, but not close enough. So if anyone can supply any info on other pistons, I'd be greatly appreciative!!!
I've been through the ACL piston and ring catalogue (pp03), so any other suggestion please?
Would also like to stay with a flat top or domed piston at the moment for the sake of compression without having to shave a rare big port head, which are harder to find than a good woman (any hints on where to find one of them too, again would be greatly appreciated, the woman that is!!!).
Clint!

Honda Accord EL 77mm, comp height 27.5 (go 1mm oversize)
Mazda E series 77mm, comp height 28.6 mm
Isuzu 4XC1 77mm, 28,2mm
As much as it pains me to say it, the Honda one is the closest. Are you sure about that comp height? It's really short....
It also helps if you can tell us what motor the piston is out of.
