You can visually compare the two at below link. I’ve organized them for easier comparison below the link.

Thanks for the comparison images! I was actually comparing those last night and was gonna post them, but you saved me the work!

I mean looking at those images I can't spot any differences.

I think at this point I'll just have to visually compare the two pumps and see if any of the pathways are actually any deeper or anything.

You're welcome for comparison images, they’re easier to compare when side by side. As far as pressure spring difference, I don’t see why you couldn’t just take spring out of your TT pump and put it in a new NA pump. I don’t recall anybody mentioning relief springs breaking in the pumps, mostly gear set wear/crack or case wear.
