Dirty, scratched, looks like they were mounted
This was exactly what I needed and in perfect shape.

Another quality set of cylinder heads. Installed on customers truck. Test drive after repair. With the o-ringed heads. This truck makes 8 psi of cooling system pressure at wide open throttle at 25 psi of boost.
Has some nicks on the head and head of a valve is pretty dirty.
Excellent customer service and quality work. Highly recommend.
