Piston ID Please

Hey guys! These are the pistons from my recently purchased ebay 521 stroker kit. They are advertised as Wiseco but I don't find any identifying marks at all. Contacted Wiseco and was told the biggest piston they offer is a 478. Maybe custom built by Wiseco so no numbers?
Trying to figure out what compression with 84cc heads. Pretty sure it's going to be more than 91 pump gas will support. lol May need to trade for some dish pistons.

Anyone recognize these?

Wiseco for sure. Reliefs for regular and SCJ heads. look to be for a stroker combination since the pin is in the oil ring groove. Depending on the head and the stroke , they could be from 11-15 to one.

Awesome! Thanks gt350hr.

Looks like I'll be needing different pistons.
