Get some flapper bits with various grit. (150, 220, 400, 600. 800) Work your way up. I'd stop near 220 or 400 grit. Just remove the casting marks.

 

the hight the number the smother it is right?

Nobody is going to see the inside of your intake. Going smoother than 400 grit is a waste of time if you are seeking performance. To put things into perspective, you can polish a crank journal with 400 grit.

 

ok..i see what your saying
