actually whats going on is I was considering an ebay set of iron EQ's (class rules) & the guy gave his # & said he could put whatever springs in that a buyer wanted along with brass guides (liners?) so I wanted to figure the valve lift of my intended cam so I could have him select the right ones but when I spoke with him all sounded good except he wanted me to pay him direct so that he could get out from under the ebay fee. I'm not comfortable with that. still undecided. I agree with him that these heads are getting real scarce until the next batch of 100 (his number) is made over there in new zealand & made available but 2K is alot to risk if he ain't on the up & up. if he wants to get over on them he might want to get over on me.
