How high can i raise the bars on a 2018 m8000 without splicing cables and wires?

This year i upgraded from a 2014 m8000 snowpro with telescoping bars to a 2018 m8000 stock. Im 6’3” and with the stock set up I’m hunched over quite a bit compared to what I'm used to. Does anyone know how big of a replacement block i can go with without splicing any cables and wires?

Ive got a Rox 6-9 adjustable riser on my 18 MCat. The cables seem to be about maxed out when the riser is al the way up.

My used to have 7.5" no problems with that.

I'm 6'7" on a 19 MC and have had a 7" fixed and now have a Powermadd 5-8" (I believe) adjustable and it works fine.
