Kent Cams used to retail them (in green) and probably still do. Some of
their stuff is made by Titan (like the roller rockers they sell). David
Anton at APT might know.
In an old Kent Cams catalogue they do list aluminium as well as Ti
retainers for the A-series (photo is b&w).
I can't imagine anyone would be using lightweight retainers on a standard
cam and rockers unless the rules forced them to so 1.5 ratio is my guess.

Good question.
The green anodizing makes it hard to determine.
I have a watch that has a titanium case, and I know what the bare metal
looks and feels like.
The lightness of the retainer in my hand makes me think that it is
aluminum. But it is difficult to be certain.
Ibll have to calculate the volume and then weigh it carefully to be sure.
Is there a known aftermarket outfit that is making these in titanium and
anodizing them green?
There are no manufacturerbs markings on these.
Ibm thinking that the previous owner of this head might have had rocker
arms with an aggressive ratio.
This may be the reason why the guides were set lower to the head.
I better get this head checked for cracks. I donbt see any visible
issues, but if itbs been raced
then it might have some hidden flaw that I canbt see with my eyes.

Are you sure they are not Ti?
