Great prices!! I had just recently started hearing about the 2018 manifold swap, so that got me looking at them. Sure didn't figure a Ford dealer to have cheaper prices then aftermarket companies. As I said earlier, for only 5 extra HP that the porting gives, I'd installed the unproved unit. VMP still says you'll need the lock out pieces, but those aren't expensive. Thanks for the info willb2305. Much appreciated!
