Topic: Ever heard of Acid Porting for cast iron intake/exhaust manifolds?
I don't have cast iron exhaust manifolds on my car but I recently learned about this "old school" technique and thought it was sufficiently lemony to pass on.
Q: Has anyone ever done this before?
Seems like a wonderfully bad idea to increase the internal volume (and hopefully the flow) into/out of cast iron manifolds at the expense of material strength.

Random tidbits
- Muriatic (concrete cleaner or pool chemical), hydrocloric, or sulfuric acids (battery) are popular choices
- You can fill the intake with water and measure the amount to determine how much internal displacement you have gained
- Alternatively, you can also use a metal sealing plate the thickness of the amount of metal you want to remove (provided it's the same material). When the acid eats through that plate, you know roughly that this is the amount of thickness removed from inside
I'm curious if anyone has tried this for the Lemons car.
