Trick Flow 11r Head Review With Real Flow Numbers

[@smoa111]

Hotrod magazine tested the TFS 205 11r heads against the AFR 205 heads on the same 408ci sbf. The trick flow heads in that particular combination made 7hp more on the top end over the AFR heads. Also ZSR engines built a 374ci-- 302 based engine with a solid roller, 205 11r heads, and on pump gas it made 712hp around 7800rpm. Just a couple of examples as they are pretty decent heads. Thanks for everything you do Eric!

[@benjaminwatson7868]

To be fair that was mildly built 408 with a smallish cam

[@smoa111]

Eric had also ported the TFS intake on the ZSR engine. Pretty impressive piece for what it was for sure!

[@MsKatjie]

Yes Eric. We all love your hard work, helping us or at least me, to get an inkling into the complexities of an ICE.

Ben Alameda has great insight into what works with these head engine combo's With a ton of time slips that are pretty quick over the years He was the first to receive the twisted wedge head when first in design stage Worth a look A Great guy very switched on

Too right, there. He is unreal.

Ben Alameda is a big fan of the TW heads and he knows a thing or two! Check out his channel!

[@paulbalzarano]

There's guys out there running nearly .600 lift on stock bottom ends with the 11R heads. No piston notches, just the factory slugs

[@ToneDeafGuru]

Ben Alameda goes into the 11R heads and explains the drop off after .600 lift. He said they’re the best Street/ Strip heads.

[@MsKatjie]

I listen to Ben! I love his stuff!

I’ve done these heads before for my 410w. Leave the chambers alone, leave the short side alone, don’t touch it. I had 2.08/1.60 valves and 2.72” at the pinch, head flowed over 330cfm at .750 on a 4.030 and held it to .850, fell off around 1-2cfm past .750”. Height over the short turn helps the heads a lot. Imo they left the intake ports stock height for marketability and manifold selection.

[@WeingartnerRacing]

Are you talking about the 11r head or just the r head

[@boss_racing]

@@WeingartnerRacingsorry the 206 R

[@MsKatjie]

Experience counts so much. Thank you for the information, willingly sharing such, with the viewers. Cheers.

[@timothybayliss6680]

For sbf stuff i dont get why raised runners are such a big deal. If you had a couple spacers for the china wall and extended the intake flanges you can raise the runner all you want. The distributor mounts to the block and there is usually a ton of clearance. You could raise the runners 1/4" without even trying and probably 3/4" if you wanted a different distributor body. You are already in for a set of head castings, how much would it be for a new distributor that works with a proper port location?

[@Adrenacyde]

Eric thank you for doing this. These are the EXACT same heads I have on my 331. It's got an FTI solid roller that makes steam to just North of 8000. If an SBF Dyno Mule becomes a thing, I'll be contributing a few Sheckles.

[@paulbalzarano]

All the piston manufacturers offer a standard and a TW valve relief. In some cases, it's the same price, otherwise its less than 10% extra

[@v8packard]

DSS offers a number of pistons configured for twisted wedge heads.

[@Comet-hn3gm]

I love the enthusiasm.

[@paulbalzarano]

The intake runner is also shorter bc the twisted wedge design. In theory, the 190 on a shorter runner acts like a bigger runner. At least that's how it's been explained to me.

[@vibrant93]

Like the video. Always been an NA person. Ran the inline head for quite some time in my youth. AFR had the market with the 165 and the right cam guy for quite some time. Switched to the twisted wedge 20 or so years ago and never looked back. Kept the cam guy though! :) Would love to see a real track to track comparison of a 225cc high port vs a 225cc R head. Set up the same way, in N/A form.

[@HerrPoopschitz]

Ed Curtis? Miss the old days of him and Jay Allen bickering.

[@flinch622]

Yes indeed: if valves get stood up and the runner is not raised... short turn becomes a problem. Beyond that, there seems to be some semi settled science: n/a stops near 13 degrees, and 11 is pretty much boost territory? I haven't seen enough builds to be anywhere close to sure, but it seems to be roughly true.

[@chevyrc3623]

Dang good infor on the twisted wedge is it like in the sbc version

[@onebadbarron04]

Eric put those 15 Degree R heads on the flow bench, you will be shocked,

[@WeingartnerRacing]

I have meh.

[@josecisneros2801]

Hi Eric, I’ve been watching your videos specifically for the SBF twisted wedge heads. My little project has a set of cheap (Back then) 170 twisted heads fast as cast and I want to clean the runners, bowls, and chambers on them to have better flowing. Don’t know if you can suggest little things like intake/exh. Bowls diameter, throat percentage diameter. And a question keeps coming to my mind is ‘Is the throat centered to the valves seat or it is offset??? Those heads still mounted on the car so I don’t know how they look. Valves are Int. 2.020” exh. 1.600” and have 3 angle seats. I really like your videos and been learning a lot with your extended explanations. I already subscribed to your channel and will keep my eyes on your videos. Hope you have great Christmas Holidays 🎄 José CE

[@cgarris8674]

Nooooo, Say it ain't so Eric! Dammit, you just burst my bubble on going with 11R's over AFR's on my last build. 😂😂 Oh well, it still runs hard and I'm a little different than all the AFR cars at the Strip. I guess it's time to save up for some CHI or Higgins heads =)

[@packhousetv]

Twisted wedge heads in every test I have ever seen or read made more power than a head commensurate to it( usually by just a little bit).However, all those tests had rather small cams and a low rpm speeds. For some reason most ford dyno tests are done with small camshafts. Usually below 240 degrees of duration @ .050. So , you are probably right if those heads get used on a max effort engine.

[@barrykennedy9947]

There are shelf pistons.

[@ummduhgmail]

Lots and lots and lots of them. We're not stuck in the 90s anymore

[@jcnpresser]

Pretty sure you can get off the self pistons now for the twisted wedge heads. Have you seen the newest old man garage when Tony showed up talking about the new trick flow he’s got, pretty sure they’re a high port design, but think they did make the car a tad faster compared to the afr that was on it. Finally got the Promaxx heads on my sbf I got from you in March. Had to just kiss the intake valve reliefs in the pistons. May could’ve gotten away without opening them up but the eye brow made me nervous. Just opened that part up a touch. I mean buzz buzz and done.

[@GaryWhipple-q6w]

Good info for the Ford boys

[@drother]

Here is an experiment you can do: flow a head at 3 or 4 different levels of vacuum - you should see the port get unstable sooner at higher velocities to show everyone why you keep flowing to 1" of lift

[@timrayburn2461]

Thanks

[@MetalonlyNoGarbage]

Thanks, Eric. I never liked the original TW head. I've used them, and they did not impress me. I switched to using AFR and High Ports. Back in the day, the in the corral forums 99%of the people thought the TW was the best Windsor head ever made. And your combination was garbage if you didn't use TW heads and a custom cam from Jay Allen or FTI. From personal experience, the original TFS High Ports are a much better head than the original TW or 11R. Most really high HP NA small block Fords use Cleveland heads. I think one reason you don't see a lot of people build windors is because they don't use a head that can support the airflow demands. Use a head with 400 cfm on the intake and 230+ on the exhaust. I think ported High Ports, like the ones you used to be able to get from Fox Lake and TEA. I think Higgins, and CHI Cleveland head are about your only options unless you want to go billet. SBC and LS have a lot more selection of heads that flow close to 400 cfm.

[@slickwillyracing4020]

Bennet Racing has a really nice Highport that flows 400/300. Ask me how I know. 😂

[@edwardwood3622]

And here I thought the reduced angle heads were exactly the same but were equivalent to angle milling the heads.

[@DSRE535]

Do they have a raised runner version?

[@WeingartnerRacing]

No

[@boss_racing]

Bes does

[@davidresar8256]

What I heard was... there are better heads than the 11R... So what are they?

[@MP-pz9oe]

AFR 185

[@WeingartnerRacing]

Tfs hi ports. Brodix t1

[@vrm86gt]

looks like that R head has alot of room to raise the intake roof and fill the floor

[@edpetrocelli2633]

I tried to explain the very same thing as you just did to a guy who graduated out of some engine school in Texas and he called me every name in the book but a white man.....no kiddin.

[@MsKatjie]

What a tool!! What was it that made him get so upset? Your street knowledge? You white man!!!!! Same here, so no insult meant.

[@DaOnE51T]

For the price,… Can’t beat the promax 210’s

[@smoa111]

For a budget head I agree. You may also look at Dart's SHP SBF 210 heads part #128225 and they currently sell complete set up for a hydraulic roller for $599 each which is pretty hard to beat for a decent budget head. These are set up with springs good to .650 lift for a hydraulic roller. They are the exact same castings that Promaxx uses except they do not do the mild clean up behind the valves. Also I believe they use a 2.05 intake valve vs the 2.08 that Promaxx uses. I am sure Eric can port either head and really make them shine!

[@GTRliffe]

that turn encourages swirl

[@seanm5282]

Eric! Why man?! You bursting my bubble after I scored a sweet deal on some bare 11R castings! All the SBF guys rave about them so I grabbed these with plans for sending them to you! Should I sell them? What’s your opinion on the best affordable head for my 10.5:1 stock bottom roller 302?
