Your engine builder may not like kb pistons instead of icons. same company icon is fordged and kb is hypereutectic. two complete qualities' i wont use keith black pistons because top ring land comes off.

Autotec dome tops are awesome pistons

I would flat cut the heads as far as possible even into the intake seat
You might even get them down to 114-116cc chambers.
Then get an Autotec piston dome built to your desired comp ratio

I did this with a 4.350”X3.76 Bbc with a smooth street roller cam. And made 700hp and it loves 8000rpm on burnout pad
