prepping motor for install

[DAWG]

I found high temp rtv between the intake and heads.
im sure there wont be any vacum leaks but im concerned about performance?
I dont feel like taking the intake off to correct that issue but will try to scrape or cut most of it off.
engine runs on dyno fine but im sure i can get better flow without the RTV in the way.
whats the best approach for the removal of the RTV without disturbing the intake?
pics are of each side.
same amount just about everywhere.
