Talking heads yesterday with some freinds .
I run eddy heads on my 418 .Limited to port volume think was 285 at 600 .
Any consideration to this topic would Indybrocks verses 360-1 work as a improvement for your 408 to 422 combos ?
Heard you could get into 300s for flow with indybrocks .
Many on here don't care for indys machine work or the rocker gear ,valve job and valves .But like the heads .
Would buying the heads bare and or CNC'd be best .
Not trying to jack thread just most get confused with all the different options .
My 418 with eddies has got me into the 9's more 10.0s i'm looking to get 9.7s,9.8s with a diffferent maybe .

I have the -1s. You really need to consider the price verses how fast you wanna go. i feel if your not going to run a roller and twist the motor way up these heads are not worth the money. I got the cnc version with cnc intake and with the t&d rockers tti 1 7/8 headers the cost is close to 7500 dollars with the manton pushrods. A freind had eddies on his 408 in a cuda that flowed a somewhere in the 290s and switched to the -1s and maybe picked up a tenth to tenth and a half but was still shifting the car at the close to the same rpm and that was with a cam change from a hyd roller to a soild roller.I have a stick in mine car and by seat of the pants feel at the track it really dont come alive till 6600 and up. Motor has a bullet soild roller mid 270s at 50 and and 668 lift with 1.5 rockers. I had the indybrock on a 416 and they seemed to work fine, there rockers are allright for a mild flat tappet or small hyd roller.Car right now has 205 to 210 cranking compression

Looking at the fow numbers, I feel there is no need to get the 245cc intake runner for a 408, a simple bowl blend and polishing the runners would keep a good velocity at 2000 rpm and above. to stay in the 310 cfm range is easy with these heads, and give superior flow numbers at .200,.300 lift and .400.
I know it take a lot of cube to handle these big runners, or keep the engine revving at 5000 to get the full potential.
So for the moment, a basic port job will do the job and have room to grow if I want to upgrade again in the future........
How many cc's intake runners become too big for a 408 ?

the indybrocks do work I just ran 9.76 at 138 with a 416 at 2971 Lbs at about 800 ft DA with no tuning but I would rather have the 360-1's.
70 duster full chassis super pro 416 CNC Indybrock heads 727 w/brake
best so far 1.212 60 6.219 in 1/8 at 110.88 9.768 at 137.81 1/4

The only way I sell Indy small block heads is with our (Ferrea or Manley) valves, my finish work including guide hone, valve job, chamber blend and short turn work, our springs and usually TD rockers.
This way at least the customer gets high quality for the $$$.
For me the Indybrock's cost too much (you have to buy them complete with rockers from Indy)to start with...
I'm going to hand port a pair of 180cc oval port heads for a bracket engine I'm building to sell so I'll post pics and info here when that happens...maybe 2-3 weeks.
Then I'll post cost of all the parts.
Brian
That will be very intersting to see...

i ran the 230cnc on a pump gas 10.5 414cast crank stroker with too big of a cam 276/280@50 and still ran 10.30s-40s in a 3400lb stock suspension dart.i really wanted the 245cnc opened up to max for a future build but ryan talked me out of it because it would have been a dog on the 414.i wish i woulda went with my instinct because i bet id be in the 40s instead of 9.60s with the new motor thats in the same car now.if i was you go the 230s they are an awsome in the middle head for the sbm. 
I actually converted a set of 230 CNC's to 245's on customers 454" motor Changed nothing else (just had ICH run intake ports back through CNC to 245) & it did'nt gain anything. The 230 head is pretty good piece.

wow interesting i figured i shoulda been worth a least a tenth.now im not so disapointed......what was the story on the intake manifold?fully ported on both or ootb square vs oval only diff.what was the flow diff btw both heads?also just to clairify i woulda went your 255cc version of the 245 not ootb indy cnc.but by the looks of things probably wouldnt have made much more of a diff espicially for the money spent.

Dominator converted INDY, port matched to Rectangle when head went rectangle...
The head is identical except just more material out of floor/roof & corner radius of the port walls, basically just adds CSA & slows air speed down some. That particular motor just did'nt respond to it.
