Tearing into a 16v SOHC 1.3 in search of "more".

I considering a swap to the DOHC pistons to pick up a point of compression.

As a point of consideration for me, up to .75 mm oversize rod bearings are available. If I used those to offset ground the crank when I did the swap, does anybody know how much material I could knock off the top off the pistons to keep them from peeking out the top? I don't have a set of DOHC pistons to measure the thickness of the piston top.

(as a contributing factor, bear in mind I am spraying 50 HP worth of n20 on it too)

I am guestimating that if I could get away with the .75mm in offset grind (1.5 mm in throw change) , and 1mm increase from boring it to 75mm, I would end up with:
75 mm bore x 77 stroke.
This would gain me about 60cc displacement and a full point of compression.
I figure maybe 4 hp from the displacement and 5 or 6 from the compression would be a reasonable assumption.

Anyone know if there is enough "meat" there to take off?
