I have never heard of acid porting? How does that work?

Acid porting is usually used to cover up grinding and real porting work done with carbide bits shruggy It makes the cast iron look like porous cast iron again shruggy

I have four sets of iron heads being done here at the shop right now, and another set on the way.

Iron still lives on!! smile

3 sets need to be iron for what the owners are doing with the cars, another set doesn't "have to" be, but really "should" be....... The last set, they wouldn't really need to be, and if it were my decision, I'd probably use stealth heads on it, but the car owner wants to use the original heads.

not every application needs aluminum heads and/or stroker kits, but online people will gladly spend your money for you

Rarely is it less expensive to rework iron heads than buy aluminum, if there are "budget friendly" aluminum heads available for what you're building....... And that's the case for BB mopars for sure.

Oh, and I had forgotten about one set....... So, 5 sets here, another set on the way smile

I always get a Kick out of the reply's in threads like these. Here the topic of the thread is "440 Iron Head Build Only" The next time I'm at the mall and see someone making a wish and throwing their hard earned coins into the fountain... I'm going to let them do it...Despite what Moparts has taught me

My advice to the original poster is to call the guy with 5 sets of iron heads in his shop.

That reminded me....... There's actually 6 sets here...... and another on the way. wink

Oh, and that's just the Mopar heads.

I'm not sure if iron hemi heads count, but if so..... Then add another set.

Got a few others of some different make iron stuff here as well..... And more on the way.

I don't mind working on them at all.
As long as the person having them done understands that quality work takes time...... And time is $$$$.

I'm one of the few guys that still thinks there is a place, albeit limited, for iron heads. If you are looking for max power without other personal choice restrictions, iron seems silly.

But, if you are in the 500 hp or less bucket you simply don't need aluminum after market either. I am not an anti-Chinese guy, but if I can reach my goal with iron, and pay a local guy (my first choice) or a domestic guy $1600 to do work, that will be a serious consideration for me. In this power range, it is the weight savings that puts me on the fence.

The weight, and the cost/ease of getting good quench........since there are far more open chamber heads than closed for the iron lovers to use.

Not work I did, but here’s a couple of pics of a low deck intake that is being used in FAST & Super Car.

Looks nice... I wonder if the same treatment would benefit my Edelbrock RPM air-gap too? work
There are some recommendations out there to cut the divider down to near the floor...

Edited to add: https://board.moparts.org/ubbthread...ove-divider-on-a-two-plane-manifold.html
There does not seem to be a firm consensus.

I can tell you that the intake in the pics ended up that way thru testing in the car at the track.
