Polishing a head
Polishing a head
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

Do anything you want but do not polish your ports. It will separate your air/fuel mixture. People usually leave it at 80 grits.

Ever wonder why golf balls has dimples? It's there for a reason, and the reason is to reduce air resistance. When air travels over a polished surface at high speed, it tends to stick to the surface and create a lot of air resistance.
In the case of cylinder ports, the fuel will stick to the polished surface and separate from the air mixture, which is a very bad thing. Port and polish is just a saying back in the old days, nowaday no one polishes the ports anymore. You can polish the exhaust ports, but carbon will builds up over the surface very quickly. Hope that helps.

Why should I go spend 300-400 bucks to get my head port and polish my head when I'm pretty much paying money for the work. Where as I can go spend approx. 50 for a kit and spend about 12 - 14 hrs to do it myself, take the extra money and put it towards something else.
I mean, I realized that I could mess up everything... but other then that. Can you give me any real hard evidence to prove that I shouldn't do this. I'm not working on a N/A or a Turbo car (yet) so it's not like I'm doing it to get everything out of the motor. I'm just doing it to get a little more performance from the bolt ons. That, and when I do finally get a turbo kit it's been done to an extent so I only have to get it done better for when I upgrade the kit.
It's just I don't understand where your coming from. Not trying to be rude any... just questioning your motive.
