Don't mind me, I'm just an intake valve, the size of a doorknob, made of Ti...

CNC intake ports
CNC exhaust ports.
the heads don't have any large oil drains to allow oil to drain back to the valley. there are two small drains, both with restrictions installed to limit flow. one is in the first cylinders exhaust valve spring pocket, the other in the last.
interesting notes here, each head has 3 dowel pin locations, one in the middle outboard head bolt, and on in each corner inboard head bolt. the middle pin location is slotted vertically, and outer two are slotted horizontally, maintaining the head in position but still allowing for thermal expansion.
coolant enters the head through one large passage on the outside of the "V" and 6 smaller holes. coolant exits under each intake port to the radiator in a water manifold.
The heads use 6 bolts per cylinder to attach the head to the block. if you look here, on the left, there is a threaded hole, that is the 6th bolt hole, it threads into the head from the lifter valley instead of from the top and into the block.
More to come later.

Re: Billet block R07 super porn
is anyone was curious about how much this custom billet dart block cost, here's your answer.
not far from what I expected.

Nice... I hadn't been back to that thread. That's about half of what I was expecting. Dart may think they can make their NRE back by making a few more.

Re: Billet block R07 super porn
This is sweet. Need more details on the car or truck it's going into!
Off topic, would a nascar spec engine be streetable? I realize they are meant to run at WOT nearly their entire lives, just wondering if they are too temperamental for the street. A 9000rpm 750hp small block in a certain RX7 would be pretty sweet.

I've heard reports that they are very streetable. one thing is for sure, they are durable, and can take a beating.

All depends on the cam... Cam it for 6000 RPM peak power, and it'll purr like a kitten at idle; cam for 7000 peak power and it'll have a lumpier idle; race camming will be pretty raucous.
...although you could civilize a race spec cam significantly (and make more power!) with a well designed throttle per cylinder intake.

I have read several accounts that the nascar spec engines are very streetable as built.The Dark Side of Will wrote:All depends on the cam...
