the texture of the tunnel is very important to keep the fuel mixture tumbling. What you have the will lead to puddling and droplets forming, IIRC.

So should he put the intake back to like a 400 grit texture.

exhaust is nice to have that smooth years ago when ppl ran carbs the texture was very important, today with the pressures of fuel injection it isnt as critcial

cant believe i missed this post lol, youre thinking about carb's 350 my good chum... fuel injection is a whole 'nother ballgame

ever heard of velocity??????????

less turbulence in the intake port = velocity

the beauty of fuel injection
