Run KB-167's. They will be 0.012" below the deck surface, good for quench and flame travel.

Yes thinking of them pistons to bad the price in Sweden is kinda high as all mopar parts

KB-399’s . Domed, depending on what heads you're running and what the measured chambers are actually at and what your target compression ratio is

 

[plymouth1937]

Yes thats an option to but whid 63cc chambers alu heads il go whid the 167

Great plan;
I think you can run your Dcr up to about 9/1 with alloy heads. I did/do,(367 cubes) and run 87E10 in that. Depending on your cam, that could be as high as 11.3 Scr, or even more.
You can't get to 11.3 with flat-top pistons down in the holes and 63cc heads.
I think @racerdan80 is on the right track.

But if you get close at least, (to 9.0 Dcr); she'd be a heck of a runner down low.
I've had my 367 to a Dcr of ~9.25 at ~900 ft elevation, which ran gangbusters stoopid strong. and got mega mpgs as well.

Here in the states they aren't cheap either. Doug's headers for a duster with a small block and ceramic coated are around $700.

Yes i hear you many wants but few are selected
But new parts is mutch cheaper on your side of the sea if you ad 40-50% your close to over prices but i can see that used parts are often cheaper over here even cars are cheaper
