Will this kit be adequate for porting a set of cast iron heads. I also have a few carbide cutters, but nothing like the selection of cartridge rolls in this kit.

That's way over priced!
Go to summit and get one of their kits.
Just don't spin them at 5000 rpm. ::)
After you bend and break the mandrels you can cut the head off a 1/4" grade 8 bolt and file or turn
the end down to fit in the rolls.

I don't know what you're talking about with that rpm. ::) ::)
I may have bent a few.......

I got the Jegs kit foe cheaper, and also go a carbide grinder bit for the heavy stuff. I use the grinders grease that Eastwood sells on the bit, and it helps keep it from getting clogged.

You'll be pissing in the wind with that shit. I wasted a ton of time on my first port job on a 2.3 Ford. Iron is a slow grind. You watch the stone wear down on the iron. Flap wheels and rolls are not up to much iron - though the high dollar name brand like Norton are miles better then the Asian jobs. Experience has taught me carbide burrs picked up at the big swap-meets for around $10 ea are the only way to go. I learned the "special" big flute alum burrs are a nightmare being far to aggressive on alum. For alum & steel I use carbides and plenty of lube and allow lube to soak in the piles of debris as a reservoir. Fine oiled burrs leave magnificent clean "machined" surfaces. Pneumatic die-grinders are pokey, noisy, windy, frustrating with variable torque/loading and even great for freezing your fingers off. I started with a Harbor Freight elec die grinder and finally scored a magnificent Bosch 30,000 rpm die grinder that purrs like a kitten and will take a loading w/o dropping rpm at a pawn-shop for a song
