WTB Riva heads and girdle kit

[Houston GPR]

Looking to raise the compression on my 2001GPR so I can keep up with the new Kawis 310LX. I'm looking for the Riva heads I believe the 41cc and the girdle kit. I pretty much have everything else not installed though plan on doing if soon my ski only has 30hrs and ready for some mods.
Also any info on jetting would be helpful currently purchased the 110 low jets the 120 high 1.5 seat and 95 gram springs with the t adjusters.
Currently I also have a 1997 1100 ZXI and it's no competition on the top end to my 1200R. So I'm getting the old lady the new 310LX maybe she can keep up then.

Shave the standard head and with the money you save buy service kits for the carbs - if you don't know when they where last done.

Don't want a carb going lean !!!

Thanks for the response but my boat has not lost any top speed from when new. I Purchased it new in 2001 it has 30 hrs. Started riding again this year. My wife rides a 1100 Kawasaki ZXI. Low hours also. My ski hits on all 3 cyl. all the time idles great and tops out great 64.4 I phone app and has more in it. I hope my carbs don't go lean that quick. I want to do the carbs with Osidebills jettings but with the heads done I wonder if those jetting specs will be good?
