Yes, apologies forgot to post the pics.
Right hand cam is the latest profile I can confirm a 0.3mm decrease in lift over the original and the part number has changed from F3R RA5 to F3R RA6 .
what you see in the last pic is the complete kit

Thanks for posting. Let us know how it runs and if you could also post pictures of the old intake valves next to the new ones. Curious to see what they changed (if there is anything visually different)

Thanks. Is it just my eyes or is the stem fatter near the base where it cups out (referring to the 2019 valve)?

Correct, the original valve narrows for the last 15-20mm before the head, and the latest one does get fatter.

Also there is a stronger Ti alloy used, it's the same alloy that the exhaust valves are made of.
