World Products head identification

went to their website, couldn't find any numbers to match up. They're sportsman IIs, but I don't know for sure what combustion chamber size they are. here's all the markings I could find:
W (left side)
K20 (left side)
94 (left side)
NH (middle)
037-1 (right side)
1 (right side)
the intake ports being the reference point. There was no markings on the bottom of the intake ports.
Thanks.

You won't know for sure what the combustion chamber size is until you CC them.
its easy.

The published spec is a nominal spec. your mileage may vary.
