440 compression boost

There are many off the shelf pistons that will get you compression with what i'll assume is an 88cc chamber head, one of which is a KB hyper piston. I've used them with an 88cc 906 head and yielded 10.5:1. Those heads were blueprinted as well. Surprisingly the chambers didn't vary as much as you'd think for factory junk.

When you get looking at a set of pitons with rings you are pushing towards 1,000, then the cost of building this engine, only to put stock heads one it? This makes no sense. I mean, maybe, if you could literally do it all yourself, which very few can. I'd be more inclined to get your self a stroker kit for 88cc heads. Then you are only looking at a potential heads change down the road which you can do yourself in the car.
