Notice the port finish....not polished but certainly not burr.

If you scroll down to the last chamber photo(before the photos of the block) those intake ports are pretty smooth, but really what do those F1 guys know?

Yes, Awesome link OP. But I was also amazed by the lack of burr finishing.

Interesting to study; thanks for posting.

I'm sure they know more than almost anyone else on F1 engines. What ever refinement issues they ran into with those straight, round ports were likely different than what SBC, BBC, etc. guys ran into with theirs.

No doubt

Is that a 40* seat with a 30* top cut or two top cuts?

I posted this for general knowledge knowing

Full well that ports etc are not very applicable

But the Technology fascinated me and the mechanical

Art and technology also .

Gary C here are the valve seats

The best thing about Brian's linked amazing article and pics is this is the most complete and comprehensive breakdown and explanation of the intricacies of complex sand cast cylinder heads, both explaining methods and the physical and material methods needed to accomplish a complete cast cylinder head.

Most users and enthusiasts usually just think someone carves out a simple mold and aluminum is poured into the mould and out pops a complete cast head! Taking ones self through these pictures and descriptions enlightens one as to how difficult and complex the process is. Very well done!

Yes I saw those thats why I asked, I know you can't compare what works on an F1 port to what we do.

I looks like on the ex there is a port bias in relation to the seat.

Great F1 tech. I just wanted to avoid any more texture debate. For the rest of my life...or longer.

From everything I have read on the subject I would have to agree that if it shows a power increase then chances are the runner was to big to begin with, a purpose built engine like F1 or NASCAR or even a well sorted out traditional build would probably see little to no benefit or possibly even hurt power due to the runner being sized accordingly and the high air speed keeping the fuel better atomized.

With an F1 engine idling around 7000 rpm there probably isn't a lot of fuel puddling.

Actually with injectors spraying from outside bellmouth of the runners I bet there was even with the injection timing events optimised
