Help me: eBay Head Gasket hunting

[TMW]

Are these REAL Black Onyx head gaskets:
6.0 Powerstroke 03-07 Black Oynx Head Gaskets 18MM - eBay (item 300490210080 end time Apr-05-11 15:25:41 PDT)

If they are not authentic "black onyx" are they still good to use with ARP studs?


Thanks for ANY input, I appreciate your time!

Here's another set you might want to take a look at. These are the Victor Reinz from what I hear they are the exact same thing as the Black Onyx.

i see your truck in your sig and it is a 2006. if you are putting them on that truck they wont fit. your looking at 18mm gaskets a 2006 needs 20mm gaskets

Ya but mine was built 08/05. According to the door sticker

Are the victor reinz just as strong?

Anyone know if I need 18 or 20 mm head gaskets? My 2006 F250 driver side door sticker has a date of "08/05" on it

How do I know my serial number?

any idea guys so I can get this item ordered? I would absolutely HATE to order the wrong gaskets..seems my truck was in limbo there between 05 and 06 being one of the first made 06's.

What should I do? 18 or 20mm?
