Hemi Hi Po Indy Aluminium Heads

[hemicharger572]

Hi guys,
does anybody have experience with the relatively new Indy Hi Po Hemi Aluminium cylinder heads?
Couldnt find a chart that shows the flow numbers. I have red that they are supposed to be between the Indy 426-1 and 426-1RA heads

They supposed to have:
266 cc Intake Port Volumne

"this the discription where I got them from"

BRAND NEW HIGH FLOW ALUMINUM 426 HEMI HEADS. THESE ARE EXTREMELY HIGH QUALITY CASTINGS AND HAVE TOP NOTCH MACHINE WORK. HIGH FLOW VALVE JOB AND VALVES. BIG INTAKE VALVE 2.40 !!!! WITH STOCK 1.94 EXHAUST, BUT STILL HAVE LIGHT WEIGHT 5/16 STOCK HEMI VALVE STEMS!!! FULLY ASSEMBLED FOR FLAT TAPPET CAMS UP TO .640 LIFT. VITON SEALS. THESE ARE INDY / CANFIELD DESIGN. WATER HEADS FOR STREET / STRIP. NICE THICK DECK AND PORTS. THESE ARE RATED AT 450 CFM INTAKE AT HIGH LIFT. THE 2.4 INTAKE VALVE AND INCREASED INTAKE AND EXHAUST PORT VOLUME WILL WAKE ANY HEMI AND WILL REALLY WAKE UP A STROKER!!!!COMPATIBLE WITH ALL STOCK HEMI INTAKES, EXHAUST, ROCKERS, STANDS, BLOCKS AND GASKETS. THESE LOOK SIMILAR TO STOCK EXTERNALLY!!


Thanks

the heads you can see in the following link will go on a 572 cui hemi, ray barton Intake, 1050cfm QFT AN, proberbly Ray Barton Roller Rockers (1.6. + 1.5 exhaust) the Indy Big Valve max port intake Hi Po heads, bullet racing solid flat tappet cam (620 gros valve lift) / Duration @050 282 intake and exhaust
9.5:1 compression ratio.

this would be the setup.

Who makes these for Indy? Are they Edelbrock?

you mean the Hi Po heads? They are made by Indy itself.

UP!
Nobody knows anything about these heads?

It will go in a 572 hemi, the Indy Hi Po Heads, 1050 cfm QFT (4150 Series) on the single Plane Ray Barton Intake with the Ray Barton Roller Rocker System. Bullet Racing Cam that was built for the heads in combination with my rockers. So I guess it will work. I have red that the Hi Po Indys are good for 1000 HP +

I just hoped to get some "real" experiences in driving and racing any kind of mopar.

BTW: It will go in 69 Polara

Thanks a lot,
Michael
