Speed master spring issues.

I got a set of the aluminum heads and had them reworked to assure they were good to go. Recut, port matched etc..
My problem is I decided to use the lunati voodoo 703 cam and bought the recommended springs for the cam but when I went to change the springs over, I noticed they are not the same height as stock heads. Quite taller. I haven't started measuring yet but looks like I have to get some more info before I get to do the break in. Anyone deal with this? Always something when you buy aftermarket crap but I already dumped a grand into these heads after purchasing them and I got to figure out what is my next step.
