5.2 vs 5.9 complete gasket set

I went ahead and returned it to the local Advance auto. They took it back and refunded me, even though I bought it online.
They don't have the 5.9 set in stock, not even in Denver, and even if they ordered it they said they couldn't give me the same price because of the on-line discount I got.
So basically have to order the correct set and wait another week for it to show.
