Any one have expierience with Patriot, Texas Speeds heads, or something a lil more reasonably priced not affecting performance all that much. Car is going to be naturally aspirrated and street driven quite a bit but still be able to tear it up at the track.

416ci L92 Aluminum Block 4.067 Bore
Eagle 4340 Forged 4" Crank
Scat 6.125" Forged H-beam Rods W/ ARP Bolts
Manley Forged 2618 -2cc Pistons
242/242 .595/.595 Lift Cam 112 LSA
Edelbrock Victor Jr EFI Intake Manifold
Kooks 2" Headers
PRC or Patriot Stage 3 heads would work well. If you already have the Yella Terra's, no reason not to use those on any cathedral port head.

For another grand or so, the TFS 235s would be the best option.

BTW we have TFS 245's with HS RR on our LSX 454 build (still waiting to go in) so I am just curious.

Cause it works

To the OP. I am running a set of Patriot Stage 3 6.0 heads on my motor that is real close to what you have.. I made 540 rwhp and 497 rwtq through a 12 bolt w/ 4.10's on slicks w/ a steel drive shaft and a ported fast set up. I know with the vic Jr and the Accufab like you have it would make more. Not bad for a budget head on pump gas so if you are tight on money that is a good way to go. When i get the extra coin i will upgrade to one of the heads that the other guys have talked about.

Did you mill those heads at all? I see those are 72cc heads. Thanks for the info, I'm glad to see someone who has some numbers on partroit heads on a bigger cubed motor

No the heads are unmilled. For the money those heads are a great deal. On a side note...where did you get your Accufab Tb from and how much was it, if you dont mind me asking.

Thats not a bad suggestion...........But, I personally would like to have a bigger runner than 215cc for a 416ci setup. Ironically, my 416 will hopefully be running by this time next week with a set of Dart 225s that I did. They proved to be too much head for a 346, but should work well with this setup. The trickflow at $1600+rockers is around $2000. For that money, you can get a KILLER set of stage 3 6.0 heads from the top hand porters on this site. I would bet you a shiny nickel that the trickflow as cast would not match them in HP. The 235cc CNC trickflow would be a different deal.

I forgot where I ordered it from. I found the vendor off google and they were having a sale on the 4150 throttle bodies. It came with the block off plate too for $499 shipped
