Correct. Nigel using fire rings not top fuel hoops. DBrods using fire rings also, up around 40psi. They work. For a 4 bolt short block that's already together, 1/2 " studs and fire rings are a good bet when pushing it > 30psi. For a max effort deal, I'd go top fuel hoops. Lastly, having a coolant pressure safety setup in ECU to shutdown engine and even consider deploying chute is not a bad idea.

I be seeing shit...saw a Elderbrock Ls3 head with the canted valves ported and developed further from otb cnc.

Damn it's to much and why can't I have this with a Ls7 casting 😫

dark eric just said in his pri vid he got to see the libertys an they where the nicer ones out the china heads. the factory ls3 only really need the throat an valve job done..the bowl is pretty big as is.

o.p id give the liberty a shot or buy some br 3 heads or some tfs 245s.

Well the goal is too go really fast with this setup so it’ll probably see 40+ psi which is why I was looking at aftermarket heads

also the stock ported heads are on my other motor which has seen 30psi with no issue but if I can leave that motor alone and do a better set of heads that don’t break the bank and can use my ls3 intake that’s the way I’d like to go

40psi through a stock intake? Impressive. I have heard of one turbo guy running the Promags heads and liking them. Mentioned they are super thick, but super thick and China usually means cheap material. If you have to stay LS3 architecture, I would get the Brodix BR3's. I have personally seen several sets of those and they are real nice for the $$$. The Trick Flow LS3's 255's are also real nice. I still think a big cathedral head is way better overall in that combo, but there is more than one way to do things.

I meant reuse my 102 hi ram lol also want to stay ls3 so if I need to switch to dual injectors I can put an ls3 lo ram on it

I’ve got brodix LS3’s

Brodix BR3, BR9, BRA (LS3,LSA,LS9)

With the combined feature of having a rigid Brodix A-356 aluminum casting with LMEs own porting, the BR3 cylinder head is an excellent choice when looking to improve beyond the factory GM LS3, LSA, or LS9 head. Standard attributes include precision CHE manganese guides with hollow stem intake...

Worth every penny. I made the swap when my Texas speed heads started to split the castings.

With the Brodix it's like getting a some what cheaper casting just a hair in being not as good as Mast or All Pro casting CID also.

maybe, but they are still American made. LME does some good port work too so it equals out for what I can afford.

Not knocking the Brodix as it would be my 1st pick because of the price point.
$800 each vs $1100+ each as cast

I don't fuck with bitch ass LME.

I don’t anymore either. They turn their nose up at the average racer.

9 months to assemble a head and never Did.

Talked to Greg G and he referred me to Chet and the guys at West Side done in 1 week.

Read that again... 1 week although it wasn't OTB shit it was typical stuff done on the Avg SBC just being done on a LS3 head.

Brodix Ls3 heads?

Update I picked up a set of prc 260’s pretty cheap my machine shop was pretty happy with them

I use the brodix castings. for pretty much everything we do, Big chevy, LS etc
I have their BR7 heads on my whipple deal, and their BR3 on a all the boosts turbo deal we are building now
I have them put good seats and guides in every casting i get from them.
Get everything HIP treated.
Zero issues. The seats and guides and hip add to the cost of course, but well worth it
