Just diving into this today and finding the same mess as you... on a -7. My build is for an IO-360.
I sent an email to Vans and received a reply from Sterling. He didn't say anything about what plans to use, so for now I'm combining the OP-04, OP-40 & OP-27A along with the drawing that came with the Horiz FAB to decipher what will eventually be the baffles.
My kit came with the same bags 5xx, labeled as being for the -8 on the contents list, and sound like the same parts you have. (my baffles were labeled as for an angle valve IO-360? on that list) That's the issue I'm hoping Sterling will look into once the power is back on at Vans.
My guess is that the plans and inventory lists are from various dates, thrown together and poorly documented. This is the most deficient I've seen on the entire build.
So, assuming I have the right parts, and can study the drawings enough, this WILL work eventually!
Good luck to all !
