Looks pretty good. It's hard to tell from the blurry pics, but I would put more of a bevel on the closing edge. Good job

 

Well thanks for the info, just finished doing them on the good housing.

 

if you have the time, you should get them polished to a mirror finish

 

they look pretty good - especially considering that this is your first.

 

Thanks guys learned alot from this site. Does anyone has a pic of a perfect exhaust port that I can look at?

 

only picture that I could find right now ... but kinda gives you and Idea. The smoother the exhaust port, the easier the gases will flow out, and the less carbon buildup you get over time. Just don't do it on the intake ports, because you want a bit of turbulance to atomize the fuel as much as possible.

 

Do you also polish the inside of your header and exhaust ??

 

wow you wasn't playing when you said polish till a mirror finish

 

wow you wasn't playing when you said polish till a mirror finish. what did you use for you final step?

 

looking good!

 

Don't know why this is adding another post, I just wanted to edit what I wrote before. If someone can delete the double post and this post.

 

Thats not my port but its the same way as polishing any aluminum. First you wet sand, starting with about 800 grit and move up to around 2000-2500 grit( a little tip, everytime you change grit change the water so that any residue doesn't get stuck on the new finer paper), from there you can get an aluminum and mag wheel polisher like the one from mothers :

You can either rub it by hand using a terry cloth, or you can get a small buffing wheel like mothers mini buffing ball or something similar, and go at it like that. It has very fine grit in there (around 10,000 grit) and that should get it up pretty much shining like the one in the picture.

As for the question concerning polishing the inside of headers, I don't know if thats really possible, but the insides of pipes are usually already smooth enough, but adding a ceramic coating on the header could probably fill in any small imperfections and leave it a bit smoother while retaining the heat inwards. (Make sure the company that does it does it inside out, some companies only do the outside from what I hear.)

EDIT: If you're port job is pretty coarse you might have to start a little coarser with the sand paper
