NA vs turbo head
See the attached pictures of my new head. It is gasket matched, 48mm intake valves and stock exhaust valves.
note the difference in the exhaust port shape and size as well as the broken ceramic liners.
Note the bores at 240,000 miles. There are almost no scratches and only a tiny ridge at the top.
Performance is good. Really good.
