If you are on a major budget crunch, pull it apart and cut valve pockets in your stock pistons, and you will gain something for certain w a moderate cam, say a Mod S. Bare in mind your stock 3.2 USA pistons CC at barely 9:1 when all is measured, and a 10.3:1 Euro 3.2 is only 9.5:1 max with a 90-91 CC head. So these are NO where near advertised on compression. You will lose a far bit of compression additionally by cutting required valve pockets.
Hopefully you see now don't be a "half way dude" and get some well designed pistons at 9.7 ish to 1 with proper valve reliefs designed in. Then you can get a modern ring pack and other features (not to mention new xlnt cond. parts ) to get all you can . Otherwise, call Laurie at Web cam and ask what is the "most" cam you can fit in there w stock pistons. Likely it's a 993 super sport is my guess... A guess because we don't do half way engines...

Hi Kevin,

Thank you for the input.
Usually not the "half way dude" :-) , but bare in mind that this engine is for a light 914-6 build, so basically not aiming for the 300hp here.
Building 2 x 930 engines at the same time, that has taken a lot of the budget as well.
My goal for the engine is to raise the power from 231 stock to somewhere 260-270 hk, and this is obtainable with stock piston/cylinders.
Just looking for the best match to the P/C that I have
