Thinner gaskets are fine to raise the compression a bit. 0.030" gaskets will bring you up close to 10:1 assuming chamber volumes and piston deck height is optimum. If you do this, you might consider what grade of gasoline you normally have available. One other thing: if you have the matching pistons for the jugs and know which pistons go with which cylinders, I would simply break the glaze on the cylinders, install new rings, and run the existing pistons, assuming they still look good.

 

And at 10.0, you can use several different cams.

You might want to zero deck your pistons and take an additional 0.010" off the heads with that cam's intake closing. OR go back to your original plan-- new domed pistons to get that C.R. up a bit more.

 

 

As long as your cylinders are within tolerance (WITH torque plates) after breaking the glaze, you would probably be ok. I would not buy aftermarket pistons with this in mind without checking to make sure your cylinders mike within tolerance first.
