As was said, if the are titanium valves, they require lash caps to prevent the valve tips being chewed up.
Are they titanium valves?? Or do you know??

Please clarify as to the type of caps that are on that must be removed. IF they are lash caps, they must stay on the valves to prevent valve damage.
Sounds like you should contact the party you got the heads from to clarify the issue.

lash caps, intake valves
The intake valves appear to be coated titanium valves, that's why they are black. What he is trying to tell you is to make sure you have lash caps installed on the tip of the intake valves where the rocker arm rides on them. Titanium valves need a lash cap to prevent wear on the tip of the valves.
I don't think the head has a hole machined in it as someone else posted. It appears to be the original cast surface of the chamber that has not been machined during the chamber porting process. This is normal. I am sure there are areas in the ports that are untouched as well.

RE: heads
I am gettingtold the black on the valve is a cap,from what I'm questioning him on unusual coloring for a new valve...I don't have the heads yet,these are from his listing on Corvette Forum classifieds...I don't think he knows what lash caps are,he just said the label was his answer to the coloring....So waiting for his call in the morning
