Default 06 2.5 Forester Head Gasket Issue

Ok, so i have got a 06 Subaru Forester NON TURBO! Im having issues with getting the right part number on the head gaskets i need to put the engine back together. I went to the dealership and they for some reason cannot match the part number with the gaskets i need. These gaskets that were on the car now are a Multi-Layer gasket that when crushed down are roughly 70 thousandths. I know they are factory gaskets because of the Fuji logos/ Subaru etc.. I'm just not sure why the dealer cant match them up with the vin... So im not sure if the engine has been changed or what...

Anyway i figured i would post this here because i feel it gets more traffic...

The gaskets that belong on that motor are only .020" thick. It has a single cam motor... correct?

If the pistons are above the deck then get head gaskets from a 99 Legacy twin cam as they are the correct thickness. That is probably your only choice.

All the 2.5L cranks have a 79mm stroke. The 01 and 06 motors are both phase 2 motors which are below the deck and they will have the same rod length.

The head gaskets that come on this thing give me 0.40" clearance. The thickness of them crushed was 0.70" clearance which is what give me that 0.40". do you think that will be enough?? The gaskets that are on on look like the old style gaskets. They are the Thicker style and not the thin. But the dealer is saying i need the thin gaskets and it is not going to work. Did subaru switch to a thick gasket for some reason? And another thing is it has 190k miles..... so im not sure if someone screwed up..

Subaru stopped using the thick gasket in 1999 so someone has gone in and changed things. You might have a short block from a twin cam N/A motor, that would be my guess.
The dealer and you are right, it is all wrong but it will work... just not properly.

The fact that it has been running like this tells us that the clearance is not an issue.
