exactly

What's the point of modifying the internals with low compression pistons and turn around get a thicker head gasket. Pointless to me. Drop the compression to whatever you like (I prefer 9.5:1) then get a stock Honda spec Cometic head gasket. You will run into timing problems on thicker head gasket since the cam will be off. It's fixable by a few ways tho, the most common is using an adjustable cam gear.

D-series turbos makes a lot of torque because of long stroke. If you bore the cylinders out, be ready to sleeve it.

Goodluck
Next time, please ask these types of question on the turbo forum where it belongs.
