Yeah get the 105;'s becasue the 90 one cant handle the preassure from the lifts of the cam and and also u are gonna need em with the cam becasue u are gonna wana shift at 6100 rpm's and thats alot stress on 90lbs ones at that high rpm

LS6 springs are really ok for most any cam, as long as a double roller is used, and valve lifts do not exceed .550"

Even at high rev (6200-6300) the LS6 springs should be ok with most cams.
What cam are you going with?

The main concern with the LS6's is their spring rate, which is higher than that of the 105s, but as I said, as long as a double roller is used, that's really a non-issue.

90# springs are fine for an XP cam but the open pressure on the 90s is high so you have to run a double roller.
