Both heads complete for .700 roller and I am way under that lift.
I am leaning towards the Brodix Dragonslayer "as cast" with cnc chambers. Why?
I was a little disappointed in the AFR 210 CNC we put on the other truck. .2 slower than a very old set of Track 1 that had been hand-ported about 20 years ago.

Just throwing it out there to see if anyone has used or has a friend that tried the Dragonslayers.

Thanks, hope you all have a great off-season, or at least a lot of don't get to race in the winter ;-)

Hi Jok,
I am running the AFR 220 non-CNC heads on my 414.
Siebert has told me that he believes they are the best performing 23 degree head out of the box. He has tested a similar combo with the CNC and it didnt produce any more power.

I was 6.07 @ 112 at the et finals, and 6.08 in montgomery. My truck is 3050 with me in it.

btw- AFR warranties their castings for something like 10 years to the original owner with a receipt.

If you had it done, what HP did it make on their dyno?
