I saw that ad as well flipping through the August issue of MM&FF while @ work today. I thought to myself, "you're KIDDING, right? Those castings aren't good enough for a doorstop already, and you're increasing the chambers to 69cc's??!?!" Pass this bad joke up. They're about as useful as a broken dick.
IMHO, the only factory castings worth anything are the E7TE and D0OE heads, of which I have sets of both.
