porting Iron heads

[TGP37]

I get most of my stuff from Eastwood, always top notch stuff for a good price.

I second the Eastwood suggestion. They make great sanding rolls and other porting items.

I didn't see a porting kit, I guess I'd have to call for a price?

If your using an ferrous burr on a non ferrous metal it will clog quickly. If you buy a burr specific to aluminum it will not require much if any oil and will cut very fast and smooth. Dr. Air sells very affordable porting kits for the hobbyist with burrs and sanding rolls in one box.

Can you provide a link to "Dr. Air"?

OK apperently all of the tools I was using were wrong for aluminum. They cut iron in record time though.

Dremel ROFL. Do you know how many of those I burned up?

Burrs don't clog unless you are pushing too hard, stones will on aluminum. Iron and stones make a great pair lol.

I don't know how many, but I will say this, mine damn near caught on fire, melted the brushes into the plastic and everything... chipped out the old brushes (yeah I'm cheap what can I say) put new brushes in an voila! works like new, and it's not quite as bulky as my pneumatic grinder...

I never had any clogging problems unless I turned up the heat on my Dremel (30,000 RPMs). I didn't like it spinning that fast anyways because it didn't really do any better going fast than slow...

i use WD-40 on the carbide cutters when porting aluminum heads, rarely did i ever see any clogging.

According to the Chevy V6 Power Manual, those fins in the intake ports increase flow by 15%. So don't remove them.

However, the exhaust ports have some lumps in them that can be shaved down.

I would also suggest port-matching the heads to the lower intake manifold, and doing some bowl blending. But do NOT port-match the exhaust side. The exhaust ports in the heads are smaller than the manifolds for a reason (to help prevent exhaust reversion).

I've heard you can dip the grinding stones in transmission fluid and they won't clog, I would just use a carbide burr and slow it down a little, it won't clog as long as you don't spin it too fast...

Also iron doesn't clog your tooling. Not annoying enough to forgoe Al but frustrating when you're trying to learn.

I would say it's easier to learn with aluminum heads

I'm going to disagree here, aluminum is much softer than iron, so it would be easier to go to deep, or gouge the aluminum than the iron. with porting, more can very quickly become less...
