OEM suby gaskets only...save yourself the head ache...Sometimes saving a buck isn't really saving a buck after all.

 

And make sure your using brown seals and not black...

 

Brown ones will be marked NTN, NSK....blacks are generic, and will leak right out the gate sometimes.

we get lots of miles out of the subaru replacement gaskets as long as you dont trust the coating on them and coat it your self with a sealing compound i use avionic form a gasket just to isolate the gasket from coolant and oil thiss works well have done over 100 engines thiss way no combacks oh and i plane the heads myself to get perfect surfaces you can realy c the damage to the head surface when you plane it

Are the heads just warped or is it corrosion eating away at them?

I had .004" taken off of this one, got rid of all but about a dime sized spot around the small center coolant port. Thought I had an after pic but can't find it.

At the top of the pic you can see the burnout where compression was blowing past the fire ring. That was gone after the first pass at .002"
