are all the aaz gaskets the same? meaning is the felpro ( and other aftermarket supliers ) gasket equal to the stock gasket from the dealer .
is any one supplier of aaz gasket better than another ?
and about the number of holes .......
the headgasket that was removed from the 1.6 td was a 3 hole ...... do i have to use a 3 hole aaz gasket ?
or can i use a 1 hole aaz gasket on the 1.6 , due to the 1.6's smaller bore size .....
thanks guys
Not sure on the first few things but if it had a 3 hole then that is what you need to put on that is if it is called for.
The best way to find out is to take a piston protrusion measurement at each cylinder and see how high above the block you piston comes up. That is what you go by to find out what hole gasket to use. Some just us a 3 hole to keep the compression down a little or just plain lazy and don't bother to measure the pistons protrusion.
Hopefully others will chime in on the other questions.
so a 3 hole would be a thicker gasket then ? ...
if that is the case , then it might be the better choice to help maintain a better seal ....

Yes the 3 hole/notch is a thicker gasket.
That isn't going to have ANYTHING to do with it sealing.
You need to make sure the head and block are flat.
Also there is a difference in manufactures as far as material.
Victor Reinz for instance is all metal, I think Felpro has metal rings around the cyl then fiber elsewhere.
Contact myke_w on this board. He knows his stuff and can get you the info and parts you need.
Your best bet is to stick with all metal, fiber just doesn't hold up like metal ones.
On brand - preferably Reinz or Elring (OE supliers), mostly because we all know those work. I have no personal experience with the fel-pro one..
See, told ya he knew his stuff
Thanks for the endorsement Dan.
Also, just an aside.. You don't really need to use any headgasket sealing treatment with these motors.. in case you were wondering.
As a general rule of thumb if you want to know how something should be done or what parts to use, think "how would the factory do it?"
Some examples. if it's a stretch bolt - replace it, if it's important - torque it, buy the best parts you can find, use the right fluids, and RTFM (Read The F*cking Manual).
