Ok, I got all the tools to enable me to do all my own porting work over Christmas. I just ported the upper intake and polished it all up (Looks Nice) But now I think I am going to strip the powder coat and polish the upper and paint it...... Anyways I was thinking about doing my heads as well. Anyone have any experiences with this, the upper n lower is pretty easy to do, but I am nervous doing my heads.

 

BUMP

 

Do you have something to flow test them? If not I wouldn't recommend it.

 

No flow testing tools, just a digital caliper to measure what I have taken off and to make sure all ports are equal... at least thats what I did for the upper.

 

How much would you charge to port my stock intake?

here's a good site for porting e7's, has some good pics and info.

 

Porting an intake is pretty easy, heads however are not. When porting heads you need to think not only about airflow volume but velocity as well, this is why doing them without a flow bench is not the best way to go. You can just clean them up a bit and gasket match them without much risk. Remeber not to polish the intake port to mirror finish, doing so can cause the fuel/air mixtuer to puddle.

 

Ive heard of people trying to port their own heads and it not comming out so well.....

 

How would you gasket match your porting?

 

I also agree that the most you should do is gasket matching or port matching whichever is the smaller of the two. I've done tons of porting and heads aren't exactly the easiest.
For port matching, paper trace the inlet/outlet you are matching it to along with the bolt holes, then cut out the center, then line up your new mock-up with the bolt holes on whatever it is you are porting. Port until you have an exact replica of the cutout you made. Really this is the best method because it will help flow the most air and there won't be any bottlenecks, before you port match make sure you have a gasket to fit the newly enlarged holes. Or, you could port something to match the gasket you have/want to use by simply placing the gasket over whatever it is you are porting and holding it in place by shoving a few bolts through where they should go. It really is best to match the two items and find an appropriate gasket, but this can't always be done.

Just remember the golden rule: SMALL TO BIG IS OK, NEVER BIG TO SMALL, you'll lose alot of power that way.

Hope this helped a little bit, have fun!
