Hello Geert-Jan, I am making a few changes with 2161 this winter. Don't have any details to share yet as there are several things in the works. The engine is in a great shape and has been well maintained. The price is very fair as I would prefer to sell and get started on the changes I have in mind. It does include air clean to oil pan. It does not include the headers but they would be for sale separately should someone want them.
