no need to reuse subaru headbolts. reusable and it's routinely done by everyone that knows a lot about Subarus - including dealers, Rick's (General Disorder) well known shop in Oregon, Ivan of IvansImports doing dozens of EJ25's every month who resurfaces the heads and resurfaces the block surfaces, Gloyale...these guys are doing significant volume and beeen into Subarus for years - replacing headbolts is pointless. I mean you can replace them - there's just no added value. It's glorious, since it doesn't matter - we are all right!
There are two people who replaced headbolts and had repeat failures on this forum and another Subaru forum. So i think it unwise to talk about headbolts because it might encourage others who aren't very familiar to think it matters. I don't think the aftermarket headbolts caused it - but i think an improper approach to focusing on "headbolts" over other wildly known avenues like which gaskets, resurface heads, resurface the block....skipping those key steps to fancy a philosophy borrowed from other platforms (where headbolts should be replaced) is a step in the wrong direction.
whether headbolts are replaced is a platform specific question dependent on the type of headbolt used. Since 1980's (and I presume earlier) Subaru has never used headbolts that need to be replaced like other manufacturers have.
