W2 Heads
The two different flow numbers can be related to the fixture plate under the head. Other factors as well. I also have two different flow sheets for my W5 heads. The smaller bore fixture plate under the head produced lower numbers but more relatable to what I would have used them on.
1st bore plate was a 4.03. Second plate was a gigantic 4.125.
Look familiar-ish next to your numbers?
