Keep the stock length 7.35 PRs, grab a set of hardened ones for the it of extra insurance, if you're using the same heads, and same length lifters. too long or too short PR's can cause serious valvetrain noise and/or valvetrain/cam lobe/lifter damage.
Is this in a NBS or NNBS? The NBS truck stock pushrod length is 7.4, I thought that the NNBS was the same, but I've been wrong before, more than I like to admit

Thank fast brick. For the extra few dollars, that Scoggin dickey looks like a no brainer. Do they have them with the gear set too? I see your name around here alot and really value your opinion and advice? Do you think I should change the gears also. My 4.8 has 86k and I'm going with a 212/218 .523/.529 114 lsa with ls6 springs and I'm undecided if I should keep stock 7.35 push rods or get comp 7.4's. Thanks. Sorry so many ?'s just trying to buy the right stuff.
I never recomend pushrods with out double checking the clearance/pre-load but hardend ones are deffenitly a good idea.
