compression for street 383 question??

Can someone tell me if i run this bottom end kit Scat Engine Rotating Assemblies 1-40805-1 - and used 70cc chamber edelbrock performer rpm heads for my 383 chevy, will it be street usable? I want to be below 10.1 compression.... Thanx

Now i got a email from Summitracing and they said using these pistons with the 64cc head...
"Based on a .025" deck and a .040" thick head gasket the compression ratio will be about 10.47:1. Pump gas may not make it. If a Zero deck block the compression moves to 11.11:1.


So im thinking if i went to a 70cc it should put me at 9.5 to 10.1 ...
