I HAVE STAGE VI HEADS AND I AM NOT HAPPY . 125 PASSES AND HAVE HAD TO REDO THEM TWICE AND THE INTAKES ARE SUNK IN THE HEAD. JUST SO I DON'T SCREW UP AGAIN. WHAT SHOULD I BUY.

Indy sr's or ez heads that use standard rockers.

Indy Sr's or the EZ's for a relatively stock looking head after the Indy logos are ground off. Hide the oil feed lines in the rear and pop on some stock valve covers and you're in like flint.

How much Horsepower do you want to make, and how many cubes???

No "one answer" for all applications...


Cheers,

Arnie

440-1s

aready had the indy sr,s

and moved up to the 440-1 cnc 345s

Would like to be around 650 horse. Next engine will be a 500 incher.

500 cubes is borderline between SRs and 440-1 heads, or B1s. Each will do a good job for a certain application. If you get a copy of AndyFs book How to Build max-performance mopar big-blocks, he has a chart of the three most common port sizes and where the torque peak comes on for each at different motor size.
I would be shopping for Eddys up to 675 hp, Indy heads or Eddy Victors for 700 to 900 hp, or if I am going for 900 hp and above, B1s.

Where can i find that book. might answer a lot of questions

my home port SR's made 650 hp with a streetable solid cam in my first 451. that got my'71 'cuda down to 10.7@127mph in street trim. std Hooker headers work with the low deck Indy heads too.

Where are all the ProComp cheerleaders?

B1BS HEADS ARE GREAT TOO.IM MAKING 842 HP WITH THEM.

As stated it will depend on the desired application for the engine in question. Greg's outline is pretty much what we follow. Hard to beat the Edelbrocks for value. I have no first hand experience with the 440 source heads but I would think they would be pretty hard to beat as well for anything in the 600-700hp range. Provided they get a good bill of health. If it is primarily a street car I think I would want to keep the port cross section smaller to make it a more street friendly set up, especially in a heavy car. I had very good luck with Indy SR's in my Belvedere. It was 3770lbs with a 451 and SR's with the std port size and the car went 10.50's on pump gas. Worked very well for me..

The Stage VI heads are good once you get them fixed. Dwayne can take care of them for you but it will probably cost as much to fix them as it would to just by a set of RPM heads. Tough choice to make, especially if you need to by a new intake manifold.

I have had most all of them except the exotics....street friendly...Indy SR all the way and dont look back. Great head.
