- I go through the structure of the cylinder head and point out the areas to focus on while porting these heads.

Great family man and content creator 👍
Another channel that my good mate youtube.com/@G... runs has more great content on some of our Australian muscle, a very switched on guy that is doing fantastic work 👌
Thanks to all the people that have watched the video, hope you find it useful.
You will notice in a section of the video there is a DragBoss Garage sticker, these were sent to me from the man himself, very much appreciated and everyone should go check out his channel (link in the description), fantastic content filled with tech and live chats with the biggest names in the industry, well worth a look 👍
Thank you so much for the kind words Sean, it is my honor to have you display my DragBoss Garage sticker. you’re one of the few to have these. Thank you for showing them off. I try to find things that you’ve never seen or heard of before for my channel. Whether it’s racers, head, porters and tech, and soon to be whole carb tech video series, by APD. Hosted by DragBoss Garage. The quest continues for knowledge. That Cylinder Head is one of the most amazing works of art I’ve seen. It be nice if you did a live chat on DragBoss Garage, giving some of the advantage of the Cylinder Head over others. Why is it so popular. think about it Sean. 🏁🇦🇺👍
@@DragBoss351Cleveland absolutely my pleasure to show off your stickers, you run a fantastic channel 👍
I appreciate the compliments of my work, function is always first but if I can make it look good as well then wining 😁
I will definitely consider your offer of a live chat mate, in the future I might put together a bit of a history of Ford Australia in-line 6 evolution and do your live chat to go through them 👍
@@seanb250 That would be welcome, and and honor my friend. Please do
Excellent work.
I always have a giggle to those that say "Barra's dont need porting to make big power". Yet, these people miss out on an extra 80cfm, or better put, an extra 32% airflow. This means less boost (heat), and less camshaft to get the same job done.
It also sounds better!
The stock port can support about 6500rpm on a stock 4L, that head is for a 4.2L spinning to 8500rpm so the area and flow is needed, it’s all math and as you said, better efficiency means less boost and heat to achieve the numbers 👍
Very interesting, informative info for the barra enthusiast. Thank you!! sounds good for that mph!
Good video Sean
Thanks mate, I’m looking forward to seeing the grey Ute running some numbers 💪
Thanks Mr burns
@@TheHBWC your more than welcome legend 🤘
Your work and attention to detail is next level, probably the best I've seen tbh. 🏆🏆🏆
I really appreciate that mate 👍👍
Cool video, its good how the video pauses so you can get a good look
@@boblogIIIfan gave me more time to dribble on 😂😂
Your work is very nice
@@shaunobrien6425 thankyou very much 👍
Good stuff! Not much information on youtube on porting 4 valve heads.
Thankyou, glad you found it useful 👍
Those kind of flow figures could be an impressive na engine build, im trying to talk a friend into letting me build a itb na barra and i think 480hp na is quite achievable with e85 and 14-1 comp with a head like this and some 54-56mm throttles and some nice sized cams 🥹🥹🥹🥹 good video i enjoyed the content
Thankyou 👍
Yeah that Barra when the 4.2L bottom end is done calculates out to around 540hp at the crank N/A
480hp is absolutely doable. In the not too distant future I will have a video out about a SOHC that sports one of heads and ported lower half of a BBM, it will make about 450hp at the crank and then hit with 300HP of nitrous. Will be fun Ute 👍
@@seanb250 Im looking forward to seeing the SOHC vid, love the SOHC
@@1616Rotor the truck is still in the works, I’m looking forward to the final result as well 😁
Nice one Sean! awesome to see the aussie stuff on youtube :)
Thanks mate 👍
Hola muy bueno el video, podrias hacer un video sobre el dimpling o efecto pelots de golf en los conductos? Desde argentina un saludo
Thankyou very much 👍
I may do a video in the future about port dimples, it’s a polarising subject 😁
Porting looks good! No bronze guides available? Or you don’t like them?
Thanks 👍
Never had an issue with stock guides on these.
Any flow graphs on intake ports from factory and then after porting?
@@clevo351 yes I do, stock intake ports peak at 260cfm and the exhausts 196cfm
@@seanb250 Can you do a video with before and after flow charts from .100 valve lift to .500 valve lift?
@@clevo351 I can do 👍 won’t be straight away tho.
" hope you find it useful." nothing there for me ! what is the optimum IN valve dia to bore ratio, IN length, and diam to IN valve diam ratio, I always remove metal from the top of a downdraft port
( side valve is the reverse ) That port marching finish is a shocker, does not have to be shiny, but will not accept the roughness promotes vortices ???? every time you make the gases tumble + lost energy
@@bobawatsit why would you listen to my answers then considering the shocking job I’ve done to this cylinder head 😂 no more answers for you 👍
@@seanb250 NO answers to my questions WHY ? Be cause you do not know shit from chewed dates, you could have pocketed those IN valves and machined the combustion chambers for a start ! The only reason that car goes well is it has massive boost, not your pathetic attempt at a cyl head redesign, and I have modified heaps of cyl heads, with great results. I would be embarrassed to supply a customer with this CRAP !
