One of the very few guys who get a thumbs up before the video even starts. Always interesting and always something new to be learnt.

You must be up early the video has been up an hour already and it's hardly 3pm here. Thank you for another enjoyable and informative video, as it happens I didn't see the first vid when it came out so I watched them both together. Regards from Perth West Australia.🙃🙃

Interesting idea to offset the head, great content as always. Look forward to seeing it making some noise...

Graham. there is so much you can do by hand if you know how to. Good job

Great to see the 2nd Episode. That off set chamber is incredible. I have a Mk3 Raymond Mays 12 port Zephyr head, I think even this must also have the offset chamber/valves as it uses the Ford tappit cover. Are you going to flow the head in it's original and new position that would be super interesting. Also if you wanted to flow a 12 port head for comparison, I'm based in Brentwood Essex, maybe I could bring it up for a 1/2 day or something?

Just posted this on the Brooklands Cars Face Book page, for any AC Ace Zephyr guys to take a look at.

dont actually know, mk1 heads had a really wierd triangluar chamber, we suspect the engine was origonally intended to be a side valve and somne of its oddities stem from that

This is a realy good question. I never realised the combustion chamber is that far off set (I assume the head is the right way round in the pic at 0:30?). I've spent 10 minutes staring at Zephyr cylinder heads and I can't work it out. If the valve centre line was further across the bore you'd need a longer set of rockers. I can only assumed that either Ford wanted to use some carry-over components (possibly the rockers) from another engine, or they wanted to machine the head or block on a machine common with another engine already in production. The downsides of course we know (!) would be inefficient breathing, carbon build up, flame quenching and unburnt hydrocarbons (poor fuel economy, emmisions etc..). Lots of US V engines have an offset valve centre line, but I've never an over hanging combustion chamber (except on a side valve of course).

Why is the combustion chamber off centre? That's a ridiculous design.
