I just got the E-mail from AFR, the new Eliminator SBC heads are finaly out :D

Raising the Bar in Performance
Light weight 8mm valves, valve springs, retainer and lock components
Light weight parts reduce valve float, increase reliability and performance gains of 75 HP with hydraulic roller cams at 6500 RPM
Whopping 10% increase in flow at all valve lifts. Our 195cc flows 300 CFM at .550 lift :shock: and the 210cc flows 310 CFM at .600 lift!!
180 and 195cc available now! 210cc in 60 days and our all new 220 and 227 (325+ CFM) shortly there after
Most efficient, highest flowing 23 degree head available, our street head out flows our competitions race head.
No other true bolt on 23 degree head comes close!!
State-of-the-art work cell for reduced lead times.

Airflow Research’s New Eliminator SBC Head

AFR’s new "Eliminator" SBC line raises the bar taking 23° cylinder head technology to all new levels. Completely redesigned castings feature improved oil drain back, stronger rocker stud bosses, and revised cooling passages and increased flow.

A clean sheet of paper approach to port and combustion chamber designs has boosted efficiency levels dramatically with smaller cross- sectional areas flowing 5-10% more across the entire curve for increased airspeed. This all new design places an emphasis on low/midlift flow numbers providing tremendous area under the curve for better cylinder fill and produces more power through out the power range. Peak flow occurring at lower lift points allows smaller street friendly camshafts to take advantage of the new design and still make huge power.

AFR leads the aftermarket by being the first company to incorporate "Gen III" technology into their 23° product line by fitting them with 8 mm valves and lighter weight springs and retainers (a whopping 50 gram weight reduction per valve/spring/retainer assembly) which reduces valve float and improves high RPM power and reliability. Experience the latest and most profound technology in 23° SBC cylinder heads by contacting AFR, and start "eliminating" your competition one by one.

Green: Baseline with re-grind solid flat tappet cam and camel hump heads
Grey: Added a HR Cam
Blue: Added 200 CC Dart Pro 1 Platinum Heads
Pink: Added AFR 195 CC Eliminator StreetPort Heads


Here's what I'm seeing:

AFR Eliminator 195cc Streetport heads
490 hp @ 6000 rpm
480 tq @ 5000 rpm

Dart Pro 1 Platinum 200cc Heads
465 hp @ 5900 rpm
465 tq @ 4800 rpm

The power curves have the same shape, so I don't think anyone can argue the heads were mismatched to the application.

Nice that the heads made up for the low end losses of the larger cam.

The Base combo:
The Vettes original, numbers-matching 1962 327/300 HP block
Bore is 4.040"
3.85" stroke crank, internally balanced
6.00" Manley SJ Rods
22 CC Forged, Ross Dished pistons
Off the shelf Comp 282 Retro-fit HR Cam, ground on a 112* LS
Morel Retro fit HR Lifters
Comp Gold 1.6 ratio roller rockers
Weiand Team G intake, opened up to a 1206 gasket
750 CFM Carb
1 3/4" X 3" dyno headers, 18" X 3" collector extension

The Camel Hump heads have been cut for 2.02/1.6" valves plus some minor port work
