Not worth a response. You’ll never understand Corona. We’ve been over this and over this.
Question for you to ponder on today…top 1%ers will be calling you with questions-might even give you incentive to go build yet another cylinder head…where does the port start and stop?

Can you just out of curiosity Post a thread not a PM and have Your guy come on and get technical. I'll wait.
I've got a thread or 2 where the 1% came in 💥...Now I know the answer.. Don't knock a guy who doesn't think of going bigger on a build for more. What I have is enough & a love for cylinder heads.

On the sidelines this season so just sitting back and enjoying the show. For cost:performance I'm partial to a cnc'd BR7 head but with no budget I'd have a full CID top end....or my combo with a Procharger

I've had solid performance with FED/Frankenstein (cathedral port TFS and square port Brodix casting). However there are a number of reputable shops that can also get the job done....some we're all familiar with and others that cater to high end, very competitive racers that may fall off social media radar.

Talking about Sticker shock..
I've been kinda helping a guy with a build in the right direction. He has short block & all the hard parts just missing cam & valve train and the heads being put together cause they came bare. Woke to a PM we had been talking so...
It would be $7k plus with porting the intake. That's crazy...it's not a CID nor Brodix head.
I think I helped knock some of that down... I don't think all was known as $1600 wasn't needed in valves with a cam that will be under .680 lift.. That would have helped some.. he asked who to go to or call...he couldn't get ahold of Ceasar.
Referenced him over to Kuntz and use hollows... he only needs some bowl work for what he's trying to do.
get a complete cam package from one of the normal suspects...Factory rocker arms with truion kit.

of the day: To complete a set of heads is $4600- that’s with my supplied LS7 heads that come cnc"ed lol. Man I come from a conventional sbc world…what these guys spend ln heads is insane... 4 a total of $6800 in heads and parts. Geez.

Tuskey is my brother and I knows he loves him Some Cathedral heads. Now being at a cross road of Brodix vs TFS 245"s. I remembered a thread I read some time back, found it during my break. So a Ls7,Ls3 and a Cathedral head on a 402...Hmmmmm. great read.

Im digging the low buck 418ci build you shared over there but honesly i rather have the (630hp) 242 duration cam over the ( 640hp) 251/259 duration cam. They swapped to a much bigger cam and really gained nothing...
The 418 Build only made 608hp with the LS3 heads not ported... impressive horsepower there but not for a 418 cubic inch motor. (LETS remember Richard Holderner did a forged 365ci and made 590 plus at the crank)
In the END with the CNC ported heads it had a respectable 1.5 horse per cube which falls into my milk and cookies catagory. This is where i think most street/strip motors should be on pump gas with a hydraulic roller.
Great article

It allows a Huge port to be filled and not restricted for air nor fuel. It's filling the cylinder hole. 101...

Flyin" 800fwhp 8 sec pass 418?
The Ed Curtis special of Stock 6.0/6.2 short blocks using Hydraulic rollers Under .248 @ .050 with Cleaned up heads, Not ported heads to run 5.90's in Moostang's
All Factory Ls3 heads and carb intakes....
so The Factory port is toooo Large?
so How does one fill a large Runner?
Cam Lift and a 4500....
Cam spec it for whatever you need or want on overlap. Just add a Carb intake with a 4 Hole TB and as much cam lift you can live with on cost on Good valve springs.
Eat Cheaply and Enjoy.
402 shitzz out 650 with a good cam and great Street manners.
That cam you like for the 630 hp add more Cam lift & carb intake = more power. Mill the heads for a Slight bump in compression. Like for 11.5 to 12.0 that helps that Tq loss with intake change. Then on the tq loss Everyone Cries about if one switches from plastic. Rear gear the damn rear end ...3. 73 would go to 3.90 or a 4.10
3.42 would go to a 3.55 - 3.73
What Evers said to be lost really isn't lost...
oops we go back to the Hood clearance and the need for something low profile....Lowest I could go was the Low ram but it still has 4500 tb thoughts....

I spoke with some shops mentioned in this thread.
They all really seem to like the Brodix heads.
The retro style LS7 All Pro heads was their second choice but they are still mostly un-tested.
The other shops don't believe Borowski made 800 hp NA on a 427 with those All Pro retro LS7 heads. I guess we have to wait for some time slips.
They also mentioned that while Trick Flow were good heads, the rocker placement wasn't ideal and leads to poor wipe patterns unless you go with an aftermarket shaft mounted rocker or the Yella Terra rockers everyone hates (increases mass in the valve train).
A lot of the shops said for an NA application, 265 cc would be the max they would go to. Bigger intake runners are suited to forced induction setups.
My current heads are Trick Flow 245s with BTR shaft mount rockers. One of the shops said I would be trading low end power and torque for high rpm power which is fine for roll racing but not ideal for 1/8 mile or 1/4 mile where a better launch leads to the lowest ET.
All shops said a ported MSD from Tony Mamo is the best you can hope for without changing the hood and going to a completely different intake. The intake is the biggest restriction.

There are a few people doing the "short runner" mod to the MSD intakes. This gives the intake a little more plenum volume and raises your peak RPM with minimal losses down low/mid range. I still hate the MSD intake, tho.

What would you like built that fit 4.000 and bigger? Common intake and exhaust locations. Common rocker. Other than that, no holds barred! Low cost of entry but outside the box thinking.

TFS 260 TFS ls7 port into
1) a thicker deck and bigger spring pad casting ...
2) raised the runner .250 to be exact valve length min of 5.6
Copy of the RHS ls7 head which others have copied
3) Shaft mounted version ready like the Brodix BS.
More material rather a Thicker rocker pad and top of the intake runner.
You could cheat using Brodix BS casting ... although you'd need 2 raise the intake runner.
