Does anyone know where I can get the parts in the US? I really would rather not order something from the Philippines and have to wait a month to get it. I want the best quality parts I can get so I don't have to do this again for a very long time. Also what is the deal with the liners in the block? How hard are they to remove and install new ones? Would it be cheaper to just have the block machined and cylinders bored? Also how do I determine if i have a 4d55 or 4d56 head? The head I pulled off of it looks like it is not the one that came on it stock. It is Suspiciously clean..

Any help is greatly appreciated, Thanks so much!
