Formula to shave pistons to reduce compression ??

I’ll want to go as cheap as possible as there will be a compromise between cr and nitrou efficiency. Depending on where you want the sweet spot, with high duration and compression with the high duration cam I have will put power in mid to top end. With nitrous, you need to retard the timing. So with what I just described I would need to pull even more timing out of the equation. Thus reducing power. So I’m hoping that I can find a head gasket thick enough to get down to 10:1

Have you ever used nitrous? Just asking, because having more compression is really not a problem. To safely run nitrous you will need to retard your timing AND use high octane fuel (like race gas). The compression is a non-issue in my opinion...and I ran nitrous for quite a few years on motors that I built specifically for nitrous use.
