Cylinder head replacement

Hello, a repair of this significance needs to be evaluated locally -- it's impossible to know all the parts you will need until you have a tech locally evaluate it. Also, why is it needed? Try some local shops -- here is a link to some trusted folks near you: https://repairpal.com/repair-shops/subaru-repair-and-service-in-livingston-manor-new-york

Be sure the latest upgrades are included in the estimate - this problem will return if not correctly repaired.. Subaru goofed on their engine design!
