I would definitely be interested in a video showing how the valvejob is done. 
Neat CNC video.

Neat CNC video. http://www.youtube.com/watch?v=O6N-G...&feature=feedu
Just saw this on YouTube and it's pretty neat to see how the whole process works. Yeah, it's from AI but it's LT1-specific, so for anyone interested in how CNC works it's pretty cool.

that is really neat to see. my family has been in the machine shop business for a long time on the tool side and i've seen all the drills/end mills made. It's cool to see that stuff in use. All the tools are not cheap! That end mill they are using is not a cheap item for sure. And everytime he has to re-sharpen, adds cost to it as well.
I had just logged online to post it.
It is the first video I've ever even made (used the free Win Live Movie Maker) & was curious to see if there were more/less shots and angles people would like to see. There are many head machining videos on youtube, but most are on low-end machinery from haas, centroid, etc. It is tough for me to judge the editing etc. since it is something I put together, programmed, and see every day. It necessarily skips forward quite a bit since each head takes so long to machine. Those transitions and captions are something to refine a bit.
As I have time I'll be making some videos of the newen CNC seat machining process, more head machining (like helical milling pushrod clearance), etc.
Thanks for the feedback!

Very cool. I especially like the automated tool changing.
Out of curiosity, due to factory tolerances I know that our heads can vary slightly in port size, shape, and flow even among identical casting numbers and dates. Are the factory heads consistent enough to use the same exact program for every head, do you have different NC programs for each casting number, or even more tedious - do you have to measure certain reference points and manually tweak programs for differences in individual cylinder head geometry?
I've taken a few machining courses, but that was on stuff like simple 3-axis CNC mills, CNC lathes, and programmable robotic arms - nothing as high end and advanced as that amazing machine.

Very nice CNC video of how it's done, I doubt you'll see how the valves are done but I'm sure it's done on a Serdi. And people still do this by hand, it is still an art and alot of work and will produce similar results. Cool none the less.

If youd like to make another video with more angles and shots, ill donate a set of heads 
( im sure you dont have any ) )
Cool vid, looks like a cnc machine. I like how it changes bits, reminds me of noises that darth vadar makes

This X a million.
Also the material can make a big difference - older iron heads will take longer then our aluminum heads...but either way you are looking at a LOT of man hours to heavily port a set of heads properly by hand.

Yes, but the program only needs to be written from the ground up once. On the second set the hand porter is starting from scratch again...while the CNC porter can just run the program again (minus any tweaks which need to be made, like I asked about in my last post).
