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 .
