valve spring question

i bought 13 valve springs off someone on this forum and ordered 3 from summit (918's). the ones i got from summit seem to be shorter. i think they are the older .600 lift batch and the ones i bought off the member here are the newer .625 lift batch. would i have any issues running the 3 for a little while until i can find the new ones.

i am very impatient and wanna get my cam in NOW! and dont wanna wait until i can find the new springs cause summit doesnt carry them.

Why would someone sell on 13 valve springs? Makes me suspicious they are the older ones that break. Personally, I think you have 3 valve springs and 13 paper weights.

also they have different installed heights Valve opening pressures this all could possibly damage the camshaft this would be one time when patience is a virtue also are the spring diameters the same and different springs rates can effect valvetrain performance
