You can't trust numbers from catalogs. They are never right. They make quite a few assumptions that can move the ratio pretty wildly. If you're shooting for a target static ratio, you have to know your exact deck height. And if it's not square decked, you need to measure all four corners.
If you know our final bore and your exact deck height, and measured head CCs, you can use a 22cc inverted dome for the math on my slugs. I can put the compression height where ever it needs to be to get the desired compression ratio.
On the price, it depends. 2116 slugs cost more than 4032... When you start messing with strokers, that can get into oil rail supports, etc...
It looks like yours wouldn't be that bad since you're running stock length rods. If you're going to use OEM rods with a press fit pin, that'll knock the price down too since you won't need spirolocks. I've got a set of .020"s sitting here that hit 9.49:1 with a stock stroke. These are ''zero deck'' pistons that are going to be used with .040" gaskets. With a stroker crank 9:1 will be easy peasy.
The rod length and crank stroke will vary a couple thou here and there but that's not as dramatic.
A good starting point is $100 a hole plus or minus depending on what you want.
