It will be in the 100 pound range. To many variables to give sure fired answer. To bring the compression up to a larger degree you will need to make the firing chamber smaller.
You can get there in two ways or both. You can get .200 off the head and use a domed piston to enter the firing chamber.

I did both to my pulling B and C.

The only domed pistons you will find for this engine will have to be a special order from the hot rod custom piston manufactures or having a machine shop TIG and machine them to fit your application. Both are costly.
I did my own having a tool shop with the equipment.

The compression will be about the same as with the factory sleeves and pistons you just are getting a few more cubic inches of engine so the HP will go up a little bit
