How far up did you port. i am gasket matching the bottoms at least, but do not know how high to go on top. it seems that alot can also be taken out of the top. thanks

I thought you had headers, any reason why you are going with ported manifolds now?

Thanks.

i had my old set of manifold's laying around and i got a dremel for christmas, so i have been working on porting them. i am just doing it for the fun of it. it is turning out really nice. the tog's are staying on my car even when it dies

The front one is really a problem, you can only go so far with it and you will break through the metal. If you really want to open it up, metal has to be added to it. If you want to experiment, I can do some welding on them for shits and giggles.

Thats a good idea. Fillit weld then go at it with a die grinder. Zack, a dremmel is nice but a die grinder electric or air makes faster work out of it..22-23000rpms.

I added almost 3/4" of metal to mine! I was able to have no hump in the manifold whatsoever. After I polished, sent them out to Jet-hot. I've never been in too much of a hurry for headers.

What would be awesome to do is weld mild steel tubes to the stock flange. Make your own headers. I was going to make a front header in the spring if I had time.

rob, i knew there had to be a faster way, haha. i have been working on it for like 4 hours already and making progress, plus i don't know what i am using, just some sanders and stuff and cut off wheels, it looks a whole lot better.
