That is a good sign, awesome really 'cause Subaru made some bullet proof engines in the 70's, we had a freid with a 500k suby wagon on its original engine.
Also I see where folks are turbo-ing to 18+psi on the stock long block, this should be a good indication that the head gasket and mating surfaces are a solid design.
