I'm not sure what your building. Here are several near zero deck pistons (compression height of 2.06+.)
Sealed power makes a lighter weight version of the Forged 6-Pack L2355 piston called the LW2355 ($410/set from Summit.) On TRWs web site it says the LW piston also uses 1/16" ring pack compared to the L2355 pistons 5/64" rings.
The Hypereutectic piston H143CP is also nice if you don't need a forged piston, and it is only $338/set from Summit.
Keith Black has some Hypereutectic pistons in Flat top (KB237 $442/set), or step head for open chamber heads (KB236 $454/set), but the step head pistons usually require a bit more machining to set the quench height correctly. They also have a domed piston for higher compression ratios (KB363L/R Summit lists them individual Left/Right for $81.97 each = $655/set.)
