PICTURED ABOVE ARE OUR FULLY CNC'D AFR HEADS.

The AFR heads are the best aftermarket cylinder heads in the world. Quality, performance, and reliability are excellent.

Below is the flow chart for the AFR 210cc heads. The flow numbers speak for themselves. A cam in the 500 lift range on up to around 600 lift would be a very good match for these heads.

As our company founder explains it, the results you experience with the AFR heads will vary greatly by what type setup you are running. The engine combos we have dynoed are what most people have chosen to use as far as cam and intake selection goes, and we have some of the results listed below. The engines dynoed with the 210cc heads were mostly sbc 421, 427, and 434 engines in the 10:1 to 10.5:1 compression range, give or take. We also did an aggressive 406 build with the 210 heads. Normally, we use the 195cc heads on the 406 but found the 210's suitable due to the cam size of this one particular engine. All run on pump gas.

Our 421 through 434 engine ads have a selection of four different cams and these engines all come with AFR heads. This has given us a great opportunity to see how they performed. We were able to test several different cam setups with these heads. This will give you an idea on what these heads are capable of with a given combination of cam, intake, rockers, and carb. This may also help you select a proper cam for your build.

We feel the 210cc AFR heads would perform very well on a medium to aggressive 421, 427, or 434 build or a somewhat Pro-street 406. As mentioned, below is just an excerpt from our 421-434 ads. If you're using a lower lift than those listed below, then it would be fair to say the hp will drop, but not by much, providing your lift and duration are somewhat close to any of the cams mentioned below. This will give you an idea of what kind of power to expect with these heads, and it can certainly help you choose a cam and intake.

Please do understand that a cam is not included with the heads. This is just a guide to show what you may expect with a given combination when building your engine.

PART # 186755-10
Valve lift with 1.5 Rockers: Intake .600/Exhaust .581
Duration @.050": Intake .251/Exhaust .255
Lobe sep. angle: 110º

Cam choice #1 with AFR 210cc heads
This cam choice # 1 is somewhat aggressive in the 421 through 434 engines with the addition of the AFR 210cc heads. We topped it off with a set of 1.6 rockers, and went with the Hurricane single plane intake, added the Super Sucker plate, and produced an amazing 625 horse power at 6300 rpm with 550 lb ft of torque at 5200 rpm. This test was done on our sbc 434 street rod engine on pump gas. The other engines mentioned have done very close to this with the same heads and cam package. These numbers are very good for not having to run the rpm any higher than this. The horse power numbers are very accurate. We performed the testing on our new Super Flo 902s dyno. No question that the numbers are correct, as we have been spot on with all of our other dyno tests of engine combos that we knew what to expect from past dyno records. The drivability, as it's referred to, would be considered decent with this setup in a medium weight vehicle (3200-3500 lbs).

Part # 180345-10
Valve lift with 1.5 Rockers: Intake .565/Exhaust .580
Duration @.050": Intake .245/Exhaust .253
Lobe sep. angle: 110º

Cam choice #2 with the AFR 210cc heads
This cam choice (2) in the 421-434 engines with the AFR 210cc heads is the perfect all around setup for those wanting a very good bottom and mid range, yet still making excellent power at the top. This engine will use the same compression as the cam choice above. Horsepower rating would drop approx. 30-35 hp with this cam. Bottom end power comes in much sooner, and this cam smooths out around 2200 rpm. This cam will make its peak power at approx. 6000 rpm.

If your car is in the medium weight range or up to approx. 3,700 lbs, and you're wanting slightly better streetability, then this is a good cam and head choice. You still want to keep the final gear ratio at .323 but no more than a .355 would be needed for great results on the street. Keeping the gear ratio on the tall side is more acceptable with this cam compared to the other choice mentioned above. You may choose 1.5 or 1.6 rockers with this cam, but we recommend the 1.5 rockers for better low end response.

This cam should be paired up with the dual plane Crosswind intake for better drivability. The single plane Hurricane can be used, but the dual plane will have much better bottom end and mid range response. Our test engine used the single plane intake. The dual plane intake would drop peak power by about 15 hp over the single plane intake. Bottom end response would be better with the dual plane. You can also expect a longer valve train life with this cam compared to the larger cam choices.

Official dyno results on our 427 Stage 5.2 engine with this cam, AFR 210-75 Heads, a QuickFuel 750 carb, and a dual plane intake.

Official dyno results in our 434 engine with a Comp Cams 520/540 cam, these heads, our new Brawler carburetor, and a dual plane intake.

An excerpt from our engine ad about our new dyno.
As of 9/15/2013 we have completed installation of our brand new Super Flow 902S dyno. In the past, we have outsourced our dyno work. Never being able to do the research and development we truly wanted, prompted us to make the $105,000 investment. Needless to say, it's been the best investment we have ever made. Every aspect of our engines can now be monitored, calibrated, and tuned. Best of all, we can see what combos make the best power, with consideration to drivability.
One thing we have noticed is that the de-tuned engines with different cam and intake combos certainly do have less top end horse power, as expected, but the torque increase in the low rpm range is much greater than the higher horse power setup. This increase in torque down low is what you want if you're sporting around on the street, rather than all out racing. The de-tuned version of our engines will also allow you to set the car up closer to stock and increase drivability to a very high degree. Throttle response is also noticeably better.
One of the worst mistakes you can make building up an engine is to get a mismatched combination of parts. We know about combinations and how they work. Take a test drive in a car with over 400hp vs. a 300hp or less and you will then see what you’re missing. The exhaust sound under load is very pleasing. We are very pleased with everything about the AFR heads. Few if any of the others know much about the correct way to setup a set of cylinder heads.
