Cam swap done..... pushrods not even close

[fullforce]

Just got done swapping in a custom lunati cam from. Member here and with my 1.6 rrs they seem to be almost 1/2" to short, is that even possible to be that far off? Not sure what size the base circle of the cam is but obviously smaller.
In fact after installing the pushrod guide plates when I sit the rocker down over the stud the rocker body will just bottom out on the flange of the stud with about 1/4" of slack left in the pushrod.
Just wondering what everyone else measured out to, now I need to buy a length checker and new pushrods.........
