If I have this correct, the reason why it's called .port and polish. is the fact that the Intakes are enlarged some and everything is polished up smooth.

And if I'm not mistaken with this... how hard would it to polish a B18A head. I'm going to be getting a 3 angle job done (the vavles need to be reseated so I figure for the extra 50 bucks I'll take a 3 angle instead of the normal) and would like to polish up the intake and exhaust portion of the head.

If there are any websites that people could really help me out with this I'd be much abliged. Unless there's anyone out there that has done this, pm me.

Thanks
