Perfect Daily Driver 10 - Cylinder Head Porting Basics

The battle to make clean, usable power is won or lost at the cylinder heads. Here's a simple how-to that anyone can follow and duplicate at home using nothing but basic tools and a little bit of time.

[@The_R-n-I_Guy]

Before shot, description of problems, after shot, explanation of what you did and why. That's the best home porting video I've seen. Thanks again Uncle Tony

[@flinch622]

This is not so much a port, but prep and quality control for a casting that received minimal basic machining, then kicked out the door by the car company that made it. Call this a good cleanup that anyone can do, and if you want to hand it over to a porter, he can concentrate on what moves flowbench numbers. The large wall of casting flash in that bowl is beyond sad: they really didn't give a rip. If that broke loose, it's enough to destroy an otherwise good engine. It makes me think if I went back to the 60s/70s in a time machine [to place a few key rides in the family to enjoy later], the first thing I would do on every car is yank the heads off, and fix the sloppy work just like this vid shows. Could be fun, watching the dealer go slack jawed as I demand heads pulled on a brand new car before it leaves the lot...and I would not budge: no sale without my inspection/cleanup.

[@Plumcraziness]

*>>>* One other tip I'd give - especially for beginners - is to start with the port areas first to get a feel for how much material the carbide bit removes with every pass you make, and how it "feels" as the bit cuts away material. You really want to get a feel for it before doing the more intricate areas of the bowls. You're learning, so if you make any minor mistakes, the ports are a good place to learn because they are more forgiving of any minor mistakes you may make. Get a feel for how your bit cuts and feels with the ports first before doing the bowls. 👍 That, and wear safety goggles to keep metal debris out of your eyes!

[@billcat1840]

and don't fall into the trap of bigger must be better....Many times air acts differently than the port layout may suggest.

[@MLFranklin]

Yes!!! Safety glasses *and* face shield. Those chips fly everywhere. The stronger the motor in your die grinder the more they fly. I had a painful trip to the ER to remove a chip from my cornea. T tried to flush it, brush it, and flick it away by myself, but just made it worse. Even tried a magnet. I had some pretty good wrap around safety glasses, but apparently not good enough in that perfect storm of chips. Next time I'll add goggles or face shield to my list of required PPE.

[@rondyechannel1399]

Tip, if you are grinding aluminum use wax on the burr to keep it from clogging. Old candles work well. Cuts better too. Go for a multi angle valve job, as Smokey Yunick said "the valve is the obstruction in the intake path."

[@460efiguys3]

Something else to try as Wax just flings... For aluminum what's even better is a mixture of wd-40/ marvel tool oil and a touch of dawn to make it cling. We use that combo no matter the carbide type when working aluminum.

[@stevenbean9706]

why i use stone on cast and burrs on aluminum

I’m on borrowed time my engine had 299k miles when I rebuilt it with new valves and lifters, but camshaft is worn and shows copper. Can’t afford a bigger cam, so might as well increase my duration by cleaning up the meat around the seats. Thanks tony. I was having a bad day

[@lskiller1903]

[@chevy6794]

Learn something from UT every time. I always looked at porting like getting max flow at max lift. Never thought of flow just off of the seat. It totally is like more duration. Cool.

[@gordocarbo]

Not really. Valve jobs do the big stuff.

[@jamesmartin-lb6br]

Best introduction to the theory and execution of head work I have seen. Thanks Tony!

[@livewire2759]

When you're going for economy, it's not about maximum flow, it's more about EVEN flow. The more even the cylinders fire the smoother the engine runs and the more economical it will be. The best way to ensure even firing and even cylinder contribution is exactly what Tony showed here, just form the ports to the shape the casting was intended to be so they are all the same size and shape for smooth, even flow.

[@richarda996]

This is also known as blueprinting in old school tech.

[@coollasice4175]

I agree.

[@fastinradfordable]

I don’t think die grinding ports = blueprinted engine

[@livewire2759]

@@fastinradfordable I never used the term "blueprinted", which refers to machining the block to exact blueprinted specs... but yeah, it essentially IS "blueprinting" the heads. Professional engine builders might have fancier tools to do it with, but they're all essentially just a die grinder, and they also do it by hand. Mass manufacturing practices cause the castings to rarely come out anywhere close to the exact measurements, shapes, and designs that the engineers intended when they were drafting the actual blueprints. The only way to make the castings match the original design is to reshape them... with a die grinder... by hand.

[@markginter8354]

Great video; direct and simple to follow instructions. I used the same Harbor Freight Die grinder and have one suggestion: use a speed control. I bought designed for a router (universal motor) for around $20. This allowed me to slow the die grinder and the difference in controllability and smoothness of cut with the carbide burr was amazing. I made it most of the way through one head before I tried it and as a result the second head went much faster and I had better control. An added bonus was that my hands didn't feel like they were buzzing after doing the second head.

[@Oldbmwr100rs]

If you're really interested in engine tuning and building, there's a couple books out there that are very interesting. One is "Tuning for speed" by Phil irving, he was a british engine designer responsible for Triumph's 500 and 650 twins as well as a number of other designs. The other is "Tuning secrets from Smokey Yunic" Both are pretty extensive, Irving's being more engineering, Smokey's being more hands on and a lot of great information on making an engine that will perform and last.

[@easygoing2479]

I do believe this is the BEST of Uncle T's videos - he addresses clearly how anyone with hand, eye, and brain skills can improve the very heart of an engine's power production. Fascinating, and it shows that Uncle Kathy's lesser half REALLY knows his stuff! Of course, I concur with many comments about eye protection, and I would also suggest hearing protection (piano tuner here). Gloves? Nah... not with this; I'd rather feel the tool here. And we need not worry about Uncle Tony's eye protection - when he sneezes, he probably just holds his nose and blasts metal shavings all over the room.

[@neilroby4063]

Greg, where can I see your video on the same subject?

[@Carstuff111]

See, this right here is what I was trying to explain to a friend!!! That as long as you clean up the ports, remove casting flaws and make sure the area behind the valve has good flow potential, it would open up some extra power. It isn't just about opening the ports as big as they can go, but just cleaning up the path already provided. And I had experience with that with a high compression Honda B18A1 that started out with just a basic clean up of the intake and exhaust ports, what little work was needed. This said, when the head was fully ported to match the new performance intake manifold... there was an even bigger gain. This said, nothing compares to the now VTEC head on the same high compression B18A1, with its port work done and its performance intake manifold.

[@robertgalvin7081]

As usual, right to the point, and VERY well explained, anxious for my t-shirt...

[@sadwingsraging3044]

“Let your vision be like water making its way through the ports. Grind off anything that is assertive to your flow, but adjust the object impeding your flow, and you shall find a way around or through it. If nothing within you stays rigid, outward things will disclose themselves into atomized flow of gasses into and out of the cylinder. Empty your obstructions to flow, be formless. Shapeless, like water. If you put water into a port, it becomes the port. You put water into a cylinder and it becomes the cylinder. You compress it by a piston, it becomes highly explosive. Now, air fuel mixture can flow or it can crash. Be water flowing, my friend.” : Uncle Tony or Bruce or someone I forget

[@Spookydude3]

a good tip especially for people who may not to confident with a die grinder and/or uncomfortable working around the seats, look into getting some guards 3d printed to protect them. the ones I made for my engine were just 1.5mm thick and cover the contact area of the seat and 2mm below it. if the cutting head of the burr hits them it will grind through in about 2 seconds, but that's 2 extra seconds to get the cutter away from the seat when it would have instantly damaged them without the guard.
