coming home soon, still trying my darnedest, to get the ball rolling on this. any more takers? the idea here to get as many interested as possible so I can get the price per unit down. The final idea is not a 34/30 head but one of cast, similar in alloy to the 1.6 blocks. BTW, anyone got a lowdown on the exact mix of one of these, or some literature on it?
thanks,
Kevin

I want this done, not so much for me, but for everyone here, I have contacted a couple more people but here stateside, I need , like REALLY NEED an autocad saavy guy to print one for me, there is an busted aaz head just begging to be played with here. Also, I would like to iron out all of the details, on this and believe the community input/majority vote wins rule here irov vs steel, what type, changes, finished or bare, etc that way I have something other than "we are still working that out to give to the machinists, as they tend to dislike indecisiveness.

Let me know when and I will have it cast. I deal with several major casting companies that do ductile iron. One guy actually likes me
and would give me a deal I am sure.

what about adjusting the valve angle or allowing for a larger set of valves by moving them out a little further, instead of having them so close togeather,

I agree, lets do that, we need some specifics, so that we know which aftermarket valves to use, same dia? different length? need some quantitative numbers, normally I would be right on this but the fact that everything is in storage halfway around the world from me right now prevents me from doing much, sorry guys. How far apart are we planning to go. how far can we go before we interfere with the water jacket/port definition "don't want to have to use a completely different intake mani do we?" the franken motor is notorious for cold start issues, , so my next question is can we inset the valves even more to allow for more vertical travel without compromising CR, VERY importatnt questions folks.

if we move the valves out, what about the cam adjustment to compensate? I can't see a whole lot of play, without making hot spots on the cooling jacket. Insetting the valves will affect the CR somewhat, and also may cause the need to redesign the cam to work under the new specs. Just spit balling here so feel free to add or refute my thoughts.

I would need a pattern or money to make one
Then all the casting can be done. Rough cast will look different than the finished machined junk head you have.

I'm a Marine, but I'm not a complete idiot. we need to sell a lot of these to bring price down? most that would want one of these would want a new cam, however, I am sure there are those that want to keep their stock cam, so...... what to do?
also, I am offering a junk aaz head for printing purposes, one that can be cross sectioned up and dissected that won't hurt someone trying to keep one of these precious heads. I am willing to donate to a good cause here.
love,
Kevin

If you were a complete idiot, you'd be a naval officer..........
back on subject, the cam would have to change enough with the new design parameters that we would need a cam designed to work with the block, or we more then likely will see live catastrophic failure of the engine and new head on first start.

not disagreeing with you..... on either count. I was spitballing that some may be discouraged from buying one if there are too many modifications. kiss it and it will be better K eep I t S imple S tupid inevitably we will end up modding everything "ooh, let's change this, or OH! let's change that" face it we can do it better than the Germans did we have the technology, we can make it stronger, faster "tv ref." My question is should we do that??? don't get me wrong, I am just as eager to milk this cow dry as any warm blooded male with speed on his mind.

if were gonna re-design the entire head, lets make it cross flow, and twin cam, and 16v.. if were gonna change some of the design, we might as well completely change it, so its more like the later VW diesel heads from europe..

maybe a 12 valve, as we would have to use much smaller valves to still fit within the chamber and pre-cup. use the same size intake valve and 2 smaller exhaust with an overall dia. larger than the single. just have one valve tappet push two valve stems.
but insetting the valve wouldent be a bad idea, a small drop in compression 1 or 3 points, just raise the boost a few points to compansate.
what does the cross flow offer that the non c/f doesnt?
