So there isnt a small dish in the top of them? I have the same piston in a block im looking at and i cant find any info about it. But it is the same model you said up top and it is bored .030 over. These just have a dish in the top that im trying to figure out what it will do to my compression. :shrug:
 
heres a pic they have valve reliefs
