We’re piston deep into a 2006 Subaru Legacy Sedan 2.5i.
It needs a right side cylinder head. The head removed has a casting number of T25.
We have found rebuildable candidates with casting #s B25 V25 and Z25. We know that the differences equate to combustion cc’s and valve diameters but can’t find a data source to determine interchange or comparability.

Let us know if you have some helpful info. We will shower you with goodies and services!


Update: We nailed it! Found a casting match and away this beauty went. Another Golden Retriever carrier back on the road!
