Default Tell Tale Signs Of HG Replacement?

2002 Outback with 108k on it. Just took the timing belt inspection cover off and pretty sure it's the original belt, so I'll replace that this weekend with a fancy Japanese made kit I bought on ebay. NTN/Bando/Paruaut blah blah blah and they even included the cam seals, although they're not leaking. Belt teeth looked fine, but that's no reason to tempt fate. I didn't see any arrows or part numbers on the belt as I rolled it around a full engine revolution, so I'm pretty sure this needs to be done.

The bigger question I can't answer is whether the head gaskets have been replaced and I wondered if there were any obvious external signs of whether they had the newer designed gasket in place? While looking at the driver's side cam gear, I saw a white and orange dot/spot painted on the gear like maybe someone has had the belt off and did this marking to remove the heads and replace the gaskets. Am I pipe dreaming here or do these marks come from the factory like that? I see no signs of leaking coolant either on the ground or as low reservoir levels, so the symptoms aren't there.

PO(who was the original owner) apparently had all his work done at the dealer, but Carfax didn't stir up any repairs of the heads.

Any help would ease a troubled mind....sorta.

Thanks

Im not sure that there would be any external signs unfortunately. I would think that the dealer would have service records somewhere for your car if you give them the VIN.

Not sure about the external sign part though... any other advice from anyone?

^^ probably true. If you are running the Subaru coolant conditioner you should be just fine weather you have the newer gen headgaskets or not. If you are not using the conditioner, its only 2.50 a bottle at any dealer...

But yeah, probably not too much to worry about
