Works of art!!!!!

Here's mine just arrived yesterday.





A look down the intake port. I can stick my fingers in and feel the transition between where they cnc from the intake side down in, and where it meets up with cncing from the chamber up on the short side radius. VERY smooth transition.



A look at the exhaust. I fondled it for a few mintues, very sexy. Notice the 8mm stem. EXTRA FLOW for the win!!!



Chamber detail.


Notice the quarter for size reference. These valves are BIG. That's lint on them btw, there is a light mist of oil or something on the valves.



Another intake shot.

 

Please no more pm's about my old heads, I am keeping them for now. I will still be running the 350 for a few months come spring time. Got to get it into the low 11's as it sits.

 

Those are Pretty. Eliminators right?

 

Yes. Ordered then on a tuesday, arrived 15 days later. They build the 227's per order. Packaged very well I might add.

 

FWIW...I picked up approx 5 MPH in the 1/4 with a swap from GTP LT1 heads to my current AFR 227's....The heads and a single plane intake were the only change to the combination

 

Im sure the single plane intake did a lot of that. Dont get me wrong though, I love the AFR's.

 

the single plane has not been proven as a big increase in power with the RPM band I am using....I am still runnig a hydraulic roller cam and lost a little more than a point of compression with the new heads also. I also increased the quench by .020

 

Yea an SP only gains above 6200 rpm and maybe 20 hp only if you can use it.

 

did you just use a girdle or did you have the offset shaft mount rockers and etc.?

 

T&D Shaft Mounts.

 

Guys,

Just an FYI....

You can run inexpensive stud mount style rockers with our 227 Eliminators (and upcoming 235 head) which has the exact same valve/stud spacing and geometry.

We sell a complete 1.6 ratio kit that has a small .050 offset pushrod cup for the eight intake positions (and eight centered for the exhaust), that works out very well and centers the roller tip of the rocker arm directly over the valve stem using the AFR supplied guideplates.

You dont need to drop big coin on a shaft system to run our larger SBC heads unless you need/want the ultimate bulletproof valvetrain and are willing to pay for it (not unlike any other head you would consider a shaftsystem for). For hydraulic roller applications and moderate street/strip solid roller stuff save your money and opt for the unique studmount kit we sell for about $325 complete. Its more than adequate to get the job done and the valvetrain geometry works out quite well.

Hope this helps....

-Tony

 

well...i think im more interested in the 227's than i have been in the past because of that post...now i gotta find a lt4 intake

 

Do you have any links to this kit, and what it all comes with? I was under the impression for ages that anything over the 210s needed shaftmounts for a street/strip HR setup - I believe it was even posted on the AFR site in the heads description IIRC.

$325 for the valvetrain kit is a hell of a deal compared to even the cheapest shaftmount setup, which would probably be the Probes at around $550. Most could probably sell off whatever they are running now for a chunk of that.

 

FWIW, two of my friends run the older 227cc's and neither run shaft rockers. They both run rollers with a girdle on top. Both are running solid cams too. As far as I know neither of them have ever had any problems. Both motors are nasty too. One is a Shafiroff 434 SBC with a big shot of nitrous in a heavy 3rd gen. The other is a nasty 406 in a ------ that's setup for some money races in --------, lol.

I'm also interested in this $325 set of rockers. I'll have to check it out.

 

Those look awesome man, keep us posted.
Someone (a friend, not a vendor) talked me out of AFR a few years back and I've often wondered how they really perform.
It seems like a lot of the guys here with impressive setups run AFR (direct from AFR or ported elsewhere),
either because some of the other options were not available at the time or because they have a great reputation.

 

Yo PUCK, I found it:

part number 6036

6036 SB Chevy HS Roller Rockers .050 Offset 7/16 x 1.6 $328.00

should save a few bucks!

 

Yep...those are the rockers we sell I have been referring to Joel.

Been sidetracked the last few days.

Those rockers work perfectly with the stock AFR guideplates. There are literally hundreds, perhaps thousands, of AFR 227 headed combo's running them with zero issue.

Good bang for the buck for a guy not looking to go shaftrockers....also, just to confirm, the same rockers will work on our new 235's soon to be released.

Thanks,
Tony

 

Tony,

Any idea what kind of pricing the 235's will see? Also, will they only accept aftermarket single plane manifolds?

~Thanks

 

Thanks,

I PM'd you yesterday and not sure if you got it or it got buried in your inbox. It was a question about milling some AFRs that have already been ported - just wanted your opinion on a safe amount to shave(I calculated that I would have to go ~.042 to bring the cc's down ~7-8). I also am not sure if I did that would I have to mill the intake port surfaces to seal properly or if the gasket would compensate.

Also, is there any way to estimate about how much the flow would be affected after milling, or would I have to do a before and after flow benching and hope just for the best?

Sorry for the ton of questions - do not want to ruin a great set of heads. Any opinions from Tony or anyone else with experience for that matter?

 

Hey Tony, what do those comp port eliminator 195's flow around .620"-.630" lift? I have read that they go into port stall much above .600" lift, so I ask because I am considering running lift in the .620"-.630" range.
