We are now offering Subaru Cylinder Head Rebuild Service.  We start off with cleaning and pressure testing your supplied heads.  We check for common wear on the cam journals and valve guides.   We can replace, or oversize ream worn out guides .002" OS to match with OS stemmed valves.   When we replace, can use STD or oversize OD valve guides to ensure tight and proper fitment.   We also offer Bronze Valve Guides for high performance applications.   Match all of this up with performance camshafts, and lite hand porting.
