Prices? What other things do you have for sale? Pictures of the block?
They were purchased from and ported by Livernois Motorsports and Engineering in Michigan. They actually do the machine work for Ford Racing! As the photos show, they are fully assembled with valves and springs - no cams. They are very surprisingly secretive people to buy from. I told them I wanted to be sure they were appropriately spec'd for a 7000 rpm supercharged application. They were built accordingly, but don't give anyone the part numbers they use. The springs are some special single spring setup they came up with. I'm sure they are a vendor you (and I) can trust. When we had the conversation about the differences between Stage 2 and Stage 3, they informed me their Stage 2's were the only ones for a stree/strip application due to the longevity of the valve guide material. So, not entirely sure about the material, but again It's the right stuff. The heads are friggin' gorgeous and the port work is substantial. Those folks are pros.
Lmao! Sorry bud! Your text is showing up white on white background for me so all I saw was the pictures in your first post.
The stage 3's use bronze valve guides, which is softer than factory and wears much faster. The stage 2 is a good way to go for the street 
Yes, I have them. $4K shipped saves you $150.
