Default do i need a longer pushrod?

i checked my pushrods last night putting my engine together. the intake has around .045 preload and the exhaust is around .033. the comp lifter say .045-.060 prefered preload. will the .033 be ok or do i need to go up with my pushrod. the next size up is 7.425 which will throw my intake to .070. what should i do, i haven't purchased pushrods yet

If 7.400" makes them .045"/.033, I'd consider a 7.425" and getting .070"/.058". That will be well within the acceptable range of those Comp lifters (assuming they aren't the 875's)!

They are the 850 lifters. The .070 will be fine?
