Our Stage One cylinder heads are great option for anyone looking for an off-the-shelf, ready-to-bolt-on set of cylinder heads. Each set starts with a brand new set of Subaru cylinder head castings. After being inspected for any imperfections, they head directly to our spray tank to be cleaned. After being cleaned they head over to our RMC 10  Surface Mill to plain the mating surface. To ensure that all chips and debris have been removed they go back into the spray tank for one last cleaning. The heads are reassembled using Brian Crower single springs and titanium retainers with GSC valve stem seals.
