Titanium is not a good material if there is any chance of metal-to-metal contact.
Titanium galls like a mofo.
Add to the fact now you've got another different metal with differing (heat) expansion rate, and you've got one messy engine unless you calculate all the clearances correctly.
I bet it's almost necessary to run those under apex seal oil jets that Hurley Engineering was touting a few years back just to keep the apex seals from seizing in their slots...

Yep what he said,

I made my own Ti seals in 1994, they were fucked

There is a reason it is used as a rubbing block on the bottom of F1 cars LOL. MASSIVE SPARKS.

If you ever tried to grind Ti on abrasive belts, good luck you will see what we are both saying to cut it is fine (machines great!) but "rubbing" its a disaster as natural as a homo having sex.

The Ti will need some sort of coating or insert on all the seal slots to work.
