Pretty good
by Bruce from Woodinville, Washington on August 06, 2013
I had no issue with the quality of the gaskets. I wish there was a diagram or list of which gasket went where, included in the package. Most are obvious, but some are a little mysterious to me. Maybe if I disassembled further, I would see where the rest of the gaskets went??? Sealant or not, was a question too. The head gasket was labeled no sealant, but the others...........
