You don't need anything special. Just a plain hyper pistons would do the trick.

If you are still planning on using a xe274 cam then look for a piston that will make 9 to 9.5:1 cr i a 454 with 120cc chambers (781 heads).

I recommend the old school 280H cam if you go with a flat tappet cam, as it is less likely to go flat than the XE cam.
