Matching the upper to the lower is super easy. The lower's port entrances are actually a little larger than the upper's. Being conservative, you could always just do that with the pieces bolted together on a table. I wouldn't use a dremel though. A proper porting cartridge roll mandrel and cartridge roll would be best. A little faster with a carbide burr which is easily controlled, especially with speed control of the motor and it's not going to gouge. It's a "feel" thing.

The lower, for the new guy to porting, the safest thing would be to lessen the injector bung protrusion as pictured above in the lower. Back and forth, side to side, over the top of it. When it starts looking like pictured above, stop. You could put a hole where the injector seats on the other side of what were looking at above. You could leave all else alone.

As to the fins, get a small handheld tool that holds a hacksaw blade. Cut them down as close to the bottom as you can. This will save how much you have to grind off. I recommend a drill mounted 1-2" sanding drum to finish eliminating them.

 

What's the website I go to to get this done?

 

OP used tom@lonewolfperformance (who should be a user on the forums)

alternatively, supersixmotorsports.com also does it for a bit more money

 

Tom did mine. I'm very pleased with the work. He almost exclusively does them at another mustang forum.

 

Hey 14Mustangv6 I sent you a pm with the info.

 

I wish I could get it done as well, but to send the parts from Germany is a little but over it. Or does anone have an idea - should I try that myself?!?

 

I'm kind of leary of trying it yourself. You really want to make sure that you have even airflow to each cylinder so that you don't run lean on one of them and get detonation. I'd leave it to someone who has the equipment to ensure that it's done properly.

 

I will start cleaning the part behind the throttle body next week when I have to take it of to change the spark plugs. I am interested what the change will be like.

 

Let us know how that turns out!

Good luck!

 

I really want to get this done myself! What are the odds of getting ahold of a set of upper and lower I'M to get this done?!

 

your best bet is probably a local pull-a-part place

 

Wanted to let anyone who is interested know that Tom is back to doing porting jobs and looks like he is offering a discount.

Finally ported my upper intake manifold and only the upper. I used my dremel to cut out those fins and than I cleaned the area with one of the grinding bits. The lower part of the manifold I just cleaned with the grinding bit. The whole process is pretty time consuming, the cutting takes a while and the cleaning afterwards even more.
Unfortunately, I didn't take any pictures, I have been busy not to mess it up. After it all I changed my tune to compensate for the increased airflow. The engine accelerates noticeably faster, but the real change I 'll check on my next test drive ...
