Stage 5 Hemi conversion heads

I see this thread is a bit over a year old and i'm bringing it out of the grave. I too wish to use a Stage V conversion kit. Is the complete kit still sold or do i have to piece it together myself. I have 2 options to work from. I have a 0.030 over 1968 440 block that used the LY 6 pack rods. It's a shame to take this one apart as it has 12.5:1 raised pistons in it. Other option is I have a bare 1972 bare 400 block. It's going into a 67 Barracuda Formula S notchback that is 383 BB car. 383 is long gone though. I even have the Direct Connection K frame that is A body/B engine config. K frame allows either early sway bar or 73 and later sway bar.
I wrote to stagev just now but unsure if they are still in business. thanks for any guidance.
