My vx has had a alpine sc (previously installed) for about 25k miles or more, and it doesnt seem to have hurt it at all. After learning how it works I dont really think it adds any premature wear to the engine. Overall I am very happy with mine being a sc'd vx. But I must admit I also received the original head, etc., to make it stock again if I ever chose to; which was somewhat comforting.
When I bought mine, I was told make sure you dont forget to change the sc oil and it'll be fine....so far so good.
Btw, thats a very nice looking vx, and seems to be a very good price...assuming a good mechanic gives it a thumbs up.
hope that helps a little
