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.

*>>>* 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!

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.

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.

“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

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.

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.

Good stuff! I build/port and polish roughly 6 sets of heads per week(well, this year is slow as I have very few either strip or track cars as the season is postponed)...and often I'll compare the before and after on our flow bench. UT is absolutely correct when he says that you really don't need to go crazy and make it look like a museum piece. Simple contouring, blending and dulling edges will go a long way. Also, on some heads, the valve(s) may be "shrouded" by the chamber. Unshrouding is also very beneficial...albeit a little more tricky for the home mechanic. However, IF you do take your head to a shop like ours and you're getting a basic valve job...it literally takes no more work to take that shroud off with the Serdi while cutting for new hard seats or re-cutting the old. Also, it take's no more expense for the shop to really do any amount of angle work. It's simply a cutting head on the machine which will leave either 3, 5, 7 or a radius. For street cars, I usually cut 5 angles on the intake and radius the exhaust. Seems that combo works really well...along with re facing the back cutting the valves themselves.

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.

I have been abusing a carbide bit for like 10 years. Recently I used it to open holes I was trying to drill in 3/8” plate. I drilled a pilot hole and opened the hole up to 4/5” diameter. Had a bowl of water. Heat cycling that bitch all day for a week. Yeah it’s got a few teeth missing. But damn a good one is worth a thousand drill bits.

this is the first practical porting advice i have seen. most always ruin heads i knew a man Tim Conolly worked at dyno center at dodge years ago where i learned what little i know about porting. he said its like a highway you want a smooth ride fuel and air want the same. he never gasket matched either he always made a gasket for the intake and gasket for head as they set on engine and port matched the ports. gasket matching always leaves a bump or as he said a ditch in the road because gaskets are always larger than the port.

I did this on some cast iron sm blk Ford heads with 1.90/1.60 valves that I bought from Indy cylinder head years ago.....the engine is still running w/low miles in a 1983 Mustang GT that I never finished painting. I'm about to work on a 318 in a Ramcharger....this is good info! 👍

awesome video, i always hear people talking about how porting doesn't yield much in the way of results but they are testing modern engines that don't quite benefit as much as these older castings with non canted valves and fairly primitive designs that don't necessarily lend themselves to laminar flow from the factory

Only thing I'll say about heads are if each volume of each chamber are identical then the engine will not shake. Found this to be true when had a 1972 - 440 Police interceptor motor completely rebuilt with exact cam specs and all new parts bought in Albuquerque, NM at 6 Pack Racing on 4th street and prior to rebuild the engine shook because it was factor built for it was a high officials cruiser in El Paso that was brand new delivered from factory to El Paso Hwy Patrol back around 1972. I was third owner of said vehicle. I'd heard in the old days that one reason a high powered motor shook from a cam was because the cylinders were not ccd. When had motor replaced into original vehicle after rebuilt found by putting hand on motor and could fill that awesome MOPAR power but saw no motor shake. Facts of truth.

Very helpful for the new engine tuners. Keep it simple is the idea, especially for a road runner. The only things I would add is the use of a strong magnet or vacuum cleaner to pull the ground metal away and wearing a dust mask and goggles.

One of the common tems we all know is the "bowl". But I like to think of it as the "bell": done right, that is the basic profile you get on an intake port if you sawed the head in half - rounded on top, a slight taper to the walls, and a roundish flare at the opening where the valve seat is. Thanks for keeping it simple - improvements don't have to be race winning to boost the fun factor of a daily driver.

Thanks Tony your Gods Gift to building a great engine.Being a backyard mechanic all my life at age 67 this will help my build on my 340 heads when I do my tare down.I have no Idea about this motor so it may have already been done.As radical as the cam sounds with a stall converter will see.One thing I did notice is the Quick response of acceleration and it has with an 850 double pumper.After putting summit roller rockers good change of royal purple racing oil the RPMs are even quicker.I went with Straight 40 synthetic. Thank you much for your video it is truly very helpful.Hope to get my T-shirt soon

you are very lucky. when i was in your age bracket, i had to have at least 3 - 100 watt light sources (or work in direct sunlight) in order to see well enough to port heads. and yeah, i learned the hard way about brazed carbide cutters. only back then, the solid cutters were in the $10.00 - 25.00 each range. i miss working on engines so much. it was the most satisfying thing (except for the kids) i ever did.

the basic simple porting job, BRAVO! each flaw can knock a percentage of power away. investment plaster castings (jewelry) are smaller but get flaws just like sand cast will. putting all the lines straight+smoother is going to open it up 4-5% at the least, that nugget in the header side was at least that much all by itself! what you just showed combined with back facing the valves will do a LOT for making torque power out of this DD project... piston flipped 360 stroke with the "doctored" 318 heads, really nice oddball combo to start with. it'll likely out-do bottle rocket (unsprayed) when done.

Following this build closely getting ready to do a build almost identical to this one. Starting with a 360 from a 1974 motor home that I picked up super cheap. Runs great now but needs all new gaskets and freeze plugs from sitting most of it's life. Motor and trannsmission have 74,000 original miles. Want the same type of build you are doing for a fun little daily driver. Drive train will be going into a 1980 D100 short bed 2 wheel drive. Thank you for sharing your knowledge freely so others can learn.
