Stock LS1 cam base circle dimension?

I just picked up a G5X4 cam. Measured the base circle today at 1.425" dia. I believe the stock cam b.c. is at least 1.500" or maybe more.
Trying to determine best pushrod length (using stock heads)., and it's looking like I'll need 7.450"
1.500-1.425 = .075 /2 = .0375 + 7.400 = 7.4375" (right?)

And since I hear it's better to go long than short for valvetrain noise concerns, 7.450 would be better than 7.425 correct?
Thanks for any knowledgeable input. If anyone from LG reads this, I'd be very interested to know what length pushrods you'd install on a X4 cam-only car...
