Default Valvespring Identification, Please help

So heres my issue. I bought some springs from Scoggin Dickey in August of 2009. I believe they are 918s. Is there anyway anyone can verify that from this picture? I cant find any emails or reciepts from this purchase. I want to say they had .625 max lift but if anyone could verify it just by the box that would be great. thanks in advance.

Well they're PAC's...the box should say if they're 1218's or 1518's...the 1218's are rated to .600 and the 1518's are rated to .650...I prefer PAC's over Comps myself...

Thanks for the info guys. I dont have the box anymore cause I through it away. I think I remember spending about $130 so I think they are the 1218s. Im trying to pick a new cam around my current springs since they dont have much miles on them.

$130 sounds like the price of 1218's...you could always take them to a machine shop and have them tested for seat pressure if you want to be sure...the 1218's have 130# closed seat pressure and 318@1.2", while the 1518's have 130# closed, and 337#@1.15"
