I have read that as well on the black block 302 closed chamber heads, thicker material around the short turn & bowl area,
from memory read from ?Paul XF1101? He has a XF sedan drag car, runs a 351 cleveland with CNC ported closed chamber heads, ran a 9.98 when I last read up on it.
was updating from earlier CNC ported 302C heads to black 302C heads that had updated CNC program chasing more HP, to get into the 9's
 
& As I found they are rather thin in the bowl when playing on a scrap head here,

Whereabouts in the bowl is that? I didn't touch mine at all when I did a quick job on mine. Just rounded off the short turn, tapered the guide boss and opened up the throat a tad.

He's doing 10s on 2V heads? That's pretty up there, the better ported stockers are doing well to get mid-400s in hp.

Im down to 1 std bore block now sold another this morn , also im thinking of selling one of these rare single plane edelbrock manifolds for a 400 the one on thr right from the usa and cost about $430 once deliverd to oz,and the other i picked up last week end in a 400 deal,see the little repair on the underside of manifold not sure what happend there but repair job is good45a0700161600df43b0b20a250f81d28.jpg51a093e358a375de94613eb7f9142d21.jpg73ec12218e7f0a4150221f315b1fc3b6.jpgc8cd84ff6d6bb0b265b566cb4d77cf51.jpgd09f328ff909c3a0d8daa089b13fc781.jpg04cdc80c3f931f1bda0503a6c5acd25e.jpg

think it was on the inlet, my fault partly gouged the tip of the burr in that area, hadn't done any porting for a while, but is a scrap head any way (I'm good at making holes)

Yes 9.806/136mph(2018), cast iron 2V closed chamber ported by JB Automotive/John Barbagallo (former Pro Stock racer), found a thread on AFF in 2016 made 664hp@7500rpm.

A.E.D who cnc ported my crossflow head told me they recently made 550hp on a 393, back when I asked them about CNC porting 2V clevo heads.

Wow they've come a long way. Must really know their way around these otherwise tricky ports. They do flow well for a factory small block port but there are only incremental gains to be made by traditional methods. The biggest hurdle after all the bowl work is port placement. Hence why CHI completely moved theirs upwards with the 3V. To get the mixture to turn such a sharp angle on the 2V is a real art. I'd love to see how they do it.

wonder whether EFI helps in some regard here
I think generally, EFI really only improves driveability and economy. If a big enough carby is used, it can pretty much equal EFI in absolute terms of power and torque. A cylinder head still has to flow fuel and air in either case, so I don't think its port design would be such a factor.

What I would like to see is just how much EFI could improve fuel efficiency on a clevo, as they really are gas guzzlers with carbies.

ask @Jewing15 if they have any fuel economy figures of the XE wagon with throttle body efi

 

@BGDAV 408 with BIG cam etc went from not being able to use 6th (T56 and 4.11 gears) with a carby, to being able to cruise at 100kmh with the throttle body EFI

Don’t have the car with us at the moment getting dodgy fuel tank hookup looked at…

But when we get it back I’ll have a look at the Holley sniper and surely that should give me so info for you

That would be interesting, if only for the feedback ability of the TBI setup. Port injection is still king when it comes to fuel distribution and atomisation though

There is good news and better news olm8 down the machine shop says the high nickel 400 block is a gem worth keeping while inspecting he could hardly even fit a tiny steel ruler between the bores meaning there is a ton of meat on this rare block and its as heavy as fk, i never seen him light up in the face like that he said no way this is gunna be a stocker ,he even said it will handle a supercharger a4c6703b0f1c2e6780b988cc260b11a5.jpg452f9ff95cba8dbf7b853640cf5ce8e2.jpg

i guess i fluked that block and heaps of research on these 400s paid off,casting numbers i mean,hey ford did make some XE casting number 4v headed manifolds for the testing which says they were thinking of making 400 4v engines but smog killed all that ,i seen some pictures of experimental 4v manifolds wow very rare.Ford 400-4V - The Ford Torino Page Forum

Sounds like you finally found the unicorn 400

olm8 said lets try and just clean it up at 020 to keep as much meat as possible,its in the tank atm he will leave it in there for a few days then hose it down so we can get an idea on the bores it might even be ok as std ? .
With lockdown on for 3 days action man pulled the blue 302c heads out for a clean up and quick inspection b4 tanking them 0d0c1f543fac2a21e3ec1e05d8d2f27d.jpgf4fd775320ddf1a971563637074d39e8.jpg

Cleaning up the valves but i dont think the thing is meant to be like this,also dropped the heads at machine shopaca284aa3f2ad8c9304a866a4913936d.jpg8d149c4b0b9fd5d6360f1bf95f8c9e6c.jpge7f588d39331082c3b03994997cf01eb.jpg42ccdd3a332b2acba8f8a95f03b7c2bf.jpg

good old 6cylinder V8 lol 
Marks 302 sounded awesome with similar
 
Ok valves are semi cleaned up and 2 are fkd also i have to take this 400 crank so the machine shop can make sure its the same as a 351c for 1 piece rear main seal milling f3b3ddfbe5b01cecc860e10ee086f229.jpg800e3aefe2c34abb95d49b08ecdcca6c.jpg652739b27e8308f407bb3793e2b49ecd.jpg

Went to machine shop and yup all is good and why buy 2 new valves for $40 when $80 buys you a set of opens with valves but wait a sec as i turn the head over i see the rare 2 dot clevo heads these only came out on xy and very early xa 351c 1st time i ever scored these 46d77f464b246129677f8c71de4855c5.jpg3ad8bf025db4c36289e717dd39677874.jpg67540e37c92fcebc410ef1562b06cb10.jpg

i just got it cleaned up at the machine shop,so tomorrow can sus it out a bit more ect,want to see the std bore if can be saved but olm8 says buy good pistons and go 020 clean up,i was going to throw some serius coin at it to arc it up,i have the single plane intake,decent roller cam ,i have a full re co 400 crank 20/20 ,but at this stage i will probly keep it,and sit on the fence with it jack ,not really sure what its worth but be dam hard to find another one in australia as they only made them in 1971,as the chart says,high nickel,but i always end up selling stuff and then moving on to something else so who knows.
