haha yeah id have to agree maybe just a bit of a mild port job would be about the only change

I'd be interested in one if it ended up in the $500 range. I'm looking forward to seeing if you can hit the $500 -$800 range as I used to work in manufacturing engineering for a casting steel company in Canada and currently work for a top end, machine shop that does lots for heavy industry. The other question is I would have is casting/foundries tend to have a large amount of scrap(bad castings) on something complicated like this. Will there be a warranty if there are problems with the casting? Or will that be for us to deal with? Will this be a weldable alloy? If its .30% carbon or higher that is extremely difficult. If you can answer a few of those questions - count me in!

that is why I made this post, we can add collective design Ideas to make this as best a concept as possible to avoid problems in the final product. not sure about a warranty, but I will make sure that I will ask, they will be pressure tested and stress tested before they go out to everyone.

If anyone has seen Aki-76's head (or is it TurboJ?) I think that would be an avenue to go down. He ported his aaz head to the point where he needed over sized valves. His two valves (per cylinder) almost touch each other.
once we get drawings of the head and a 3D graphical of it, it should be clear how much bigger the points can get before risking structural integrity (seeing as it will be steel not soft alluminium)
Edit: at least i thought they got over sized valves. I couldn't find the pictures in the jetta 200 thread... there is a picture of a piston with big cutouts for larger lift on the valves...

Well Andy2 apparently has a cast iron head on a TDI... i just read that. Where did he find that?
I'd be very interested in casting an alluminum 16v IDI head. possibly much cheaper? but less potential i suppose.

benefits?
wouldn't crossflow be awkward with our IPs kinda in the way?
I'm not sure how I'll get the money, but I'd be interested, but want more info first.

aki, do you have a video with good sound quality of what that engine sounds like with those massive valves?

I love the pics of that head, any more? That's one hell of a port job!

best valve size is 39 in and 34 ex orginal aaz head.Bigger bore ( 81 ) can use 41 / 35 valves.That latesīt version my own head is allmost twice better flow vs. orginal.
Did you need to find larger diameter valve seats or did the stock ones have enough material left? Specifically for the 39/34 valves.
