I just purchased a the complete gasket set for 12.5KW BTBD diesel generator. part no. 46903.
It has yet to be opened. When i took it to the machine shop where the work is being done, he said there are not enough valve seal guides. There are 6 in the package. The engine is a 4 Cylinder and has 2 valves per cylinder.

Should there be 8 valve seal guides in there? What am i missing?
