This set of highport heads has 2.08/1.60 valves but no springs/hardware (at the moment). They are o-ringed and have been ported prior to my purchasing. These are 60cc heads and I have yet to run them due to purchasing them thinking they were 68cc versions. As of 10/14/10, the heads are at the local machine shop being prepped and will be complete in a week or so. Price will be $700 plus the bill for the work/material. These heads have been ported some but not to their fullest potential.
