TFS 235 vs Brodix LS7 Results On an LS3 427 with 4.125 bore.....
Car made 560 with a tight stall and 530 with a lose stall. Have TFS235s with FAST 102. How much if any power would I pick up if I switched to the Brodix ls7 style heads/intake? Compression is 11.4 and I want to stay on 93 octane. Is 30whp a stretch? I'm really looking for honest, knowledgeable answers. Max rpm is 7000.

LS7 Brodix heads I don't have my New Zealand customer's dyno sheet but he says he made 600 to the wheels with Richard's - West Coast Racing Heads CNC ported Brodix LS7 heads on one of my dry sleeved 427" 5.3 Gen IV aluminum truck blocks.
Compression ratio was about the same as what you have in a road racing application.
Intake manifold was a reworked LS7 factory intake.
Danzio Performance, one of my off road race engine builder shops using my blocks uses the Brodix heads CNC ported by West Coast Racing Heads on most of the off road racing engines he builds. These engines (427" to 434") all make over 700 at the flywheel and have proven to be very reliable.

4.125 bore
Va Speed massaged CNC TFS 235s
Ported FAST 102
NW 102 TB
Kooks 3" full exhaust
Kooks 1 7/8"
3.91 gears
4000 stall (may change to a 3600)
11.4 compression
Cam is a 23x/24x on a 114. I don't know the exact specs and I don't think Va Speed would want me to give it out. It's very mild for a 427 though.
If I can get 30whp, yes it's worth it to me. I'm an all motor guy and I love the way the car responds. I'm shooting to be the first GTO in the country to run 9s all motor.
What makes the heads so much better than the Trick Flows? I was always under the impression that they were the proven golden heads?

Do they require new pushrods, rockers and lifters? I'm sorry I don't know much about heads at all. I just know the TFS are pretty good stuff. But like the different valves, etc I'm clueless.
What's the cost of those heads? Would I benefit from more compression if I can still run 93?

Don't know how close my power was compared to your car
I make 512 to the wheels on a mustang dyno with my old set up. LS3 heads and a 23+/24+ cam
my car was running 127 on with the race weight of 3800
im switching to some WCCH powered LS7 with a 23+/25+ with a lot more lift
so ill let you know if i get 30+... but im looking for a bit more out this set up

560 to the wheels is pretty impressive already with that small of cam. I dont know if your aposed to a larger cam but texcam is getting it done with those heads and intake with a lot bigger cam. If you have that much money to spend on 25-30 hp go for it. LS7 heads work well with small cams. Might think about PI heads also. They are proven at the track out of the box. I'd be interested to see you results.
