Jason, how long ago did you buy yours.?
The price is higher now and as I said they have gotten better with the welds, all of mine were very good.
I did not feel the nead to clean any of the welds up at all. Was able to bolt them on as they came out of the box.
Just tossed the supplied gaskets and re-used the OEM steel ones.
No leaks.
