I don't think they are that low a quality! Might try a local Fastenal, You may be able to get them cheaper than what the dealer want's.

 

Here's mine after replacement of the aluminum

 

Is that the inside? Or the bottom?

 

That was the bottom . However there was a tone of oil in the inside

 

Think I would be running a high-detergent oil, and changing it every 2000 miles for a while.

 

Wrong thread

 

I also purchased an aluminum plenum plate from an eBay seller and was very happy with it. As for the factory intake bolts, I think its best to replace them as they are low grade bolts. I had one snap on me when installing my 5.9 motor into my truck. The bolts were screwed into the heads without the intake on the motor.

 

Are any of you guys selling these yet? I need on for my truck.

 

Check EBay. There are several sellers out there, almost of of 'em are cheaper than hughes.

 

Here's one - https://www.ebay.com/itm/14455439116...UAAOSwv0tVSkK1 - comes with the plate and bolts, but you will need to purchase your own plenum gasket, as noted in the posting.
