valve seat is extra hard stainless steel,only for racing use.and lot of bigger thant orginal.If you use 39mm valve,you need 40 or 41mm seat.
egine give all most 150nm torgue at 1100 rpm,and 450-480nm 4500rpm.Redline is 6500rpm.That 1/4mile video drive only half of normal boost.

thermal expansion, the mold would have to be redone, couldn't use the same one. XXX,XXX cost
Said another way, when you pour the liquid metal into a mold, as it cools it shrinks. The rate depends on the alloy. You have a large pour funnel and raisers on top of the mold that fill when you do the pour. As the metal shinks, it pulls metal in from the funnel and raisers. I don't know the difference between aluminum and steel, but tool steel we calulated 17% shrinkage. You should be able to find this on the web. It could be there is a steel alloy with a similar rate to the aluminum casting. Maybe a stainless ? :-D $$$

and way out of the realms of most of us. stainless would cost more than an arm and a leg.
i still wanna be able to give my VW throttle and shift after we get these new heads! so i will be needing all my limbs.
and when is the head going to be stronger than the block? im sure its not gonna take much to make the block the weak point.

41/40 cast steel with some machining sound good? I had a great machinist suggest it and I think it is definately in the realm of the doable

No way dude...everyone will still want it at 5,000.00, they just won't buy it
Well someone might, but not this guy

im really REALLY hoping these heads will be somewhat affordable. but the thing is, it would probably cost less for us to all buy TDI short blocks and machine up some TDI heads. then there is no need for pre cups and all that sort of machining.. crap, we could even not machine the heads for GPs for people in warmer climates. TDIs barely need GPs anyway.
ive been told the TDI head is much easier and cheaper to build.. and the engines are only capable of 3 or 400 hp or so
what are we waiting for?!?!?!
and good point Lucas.. i like your thinking.. everyone is going to be in the "just window shopping" boat if they cost too much..
i thought the whole point was to keep the heads as cheap as possible.. and every time we hear updates, they are sounding more and more expensive..
