I believe the 210’s in this article are the Mongoose version, formerly known as the 205. Excellent heads. But not the same as this new budget 210. They made things a bit confusing.

 

wasnt referencing the 205 or 210s, 215 and 230s have better flow numbers and with different bores

 

I called afr about this in the past. They are designed to be factory replacement heads. They can be messed with for power as a factory head can. These are designed for people who need a factory style head but either can't find them or pricing is insane, which depending where you are, can be. If you already have an ls6 head, these heads probably aren't for you.

 

I agree. They look like they have a better chamber and they do flow more than a 243, but for the same price, you could have 243, 706, or 862 heads ported and maybe make more power with a stronger/better factory casting.

I am very curious to see how they perform though. Especially with a good valve job too.

 

Source is AFR - 210cc-ls1-enforcer-cylinder-head website.

Flow numbers are probably a few cfm lower with a 3.9 bore since flow test was on a 4.065 bore.

 

Seems to be pretty much the equal to a 243 head.

 

......which, along with its 799 twin, is far more common since they came on every Gen IV 4.8 and 5.3 truck engine

 

Agreed at least until Richard Holdener or someone similar provides data and proves they are exceptional.

 

Does the Enforcer use bronze guides or iron?

 

Bronze alloy. Not sure what alloy.
Or if it’s the same as their higher end heads.

 

Preface: currently running stock 241s, LS6 intake, 224r cam full bolt-on. My car is set up 100% for road racing, I could not care less about 1/4 mile or dyno queen numbers. I want more power from 3000-5000 to help push out of corners and then obviously more HP/TQ would be great on the straights

Sorry to revive an old thread, but am seriously considering these AFR heads and had a couple questions if anyone has used them. Looking to replace my 100K+ mile lifters in my LS1 with LS7s for no reason other than preventative maintenance and these look like the best option right now. But, I see a lot of guys talking **** about them seemingly because for $1200 a set assembled they don't flow 10 million CFM to match up with the 269/269, 3 mpg, car sounds like a John Deere tractor redneck Ferrari cams . Used and reman'd 243/799 currently go for around $700-800 on eBay and that's if you trust the jabroni's on there did a good job machining them. I could get a set of these AFRs, fully assembled with dual springs for literally the same price versus buying a set of eBay 243s and install the same valvetrain.

So, for anyone that has used them or just looking at the flow numbers:

1. Are these a worthwhile upgrade to 241s I should slap on while changing the lifters?
2. I'm already well tuned for my current setup with 241s. Would throwing these on require a retune?

I realize there are better heads on the market for a lot more money. To reiterate, I am NOT looking for a max effort donkey-dick cam/69 million CFM heads flow build, I DD a v2 CTS-V if I want to mess around on a drag strip. I purposely have not (and will not) put a stall in the car because the extra heat would instantly murder my trans on a road course in the summer. I'm on a budget because road racing consumables are stupid expensive and I can get a set of MPS4s that will last me a whole season of time trials with the money saved versus a higher set of AFRs

 

Your cam will determine your engines manners. These AFR heads are designed to mimic 243 heads. I think they flow slightly better than factory 243/799. If you don't want to fart around with used 243. cleaning them etc, then these heads are for you.

Will you get more power out of these vs your 241s? Yes. I'd expect around 15-25 HP to the wheels with your configuration

Will you need to re-tune? No (it will drive fine) and Yes (to maximize your power). Your CR will increase with these heads, so the timing and fuel should be tweaked.


Side note - This might be a side-grade, but check out the Track Weapon Cam from CamMotion. Designed for flat as a table Torque curve 3k-5k, and gentle on the valvetrain.
