i did search and i can't find any thing

 

Gasket match the intake runners with a dremel, and then clean up/smooth the insides as best you can. Try mirror polishing it if you can.
If you don't know what this means, you shouldn't be porting an intake.
As for TB, smooth out the square edges inside it (after the TB mod) with a dremel.

 

search will only get 2-3 days worth of posts since disabled post whoring
