Replacing pushrods

[Mrturner1]

Might have seen my thread on squeaking tapping #8 cylinder. Re-used the old stock pushrods in the new top end rebuild, bad idea damage is small because I caught it in time though. I have a 355 with a comp 280H cam and guide plates in the heads. 1.52 PRW roller tip rockers (probably replacing all of them though with whatever is on the shelf at Orielly speed shop. Looking at Comp part #7812-16 which says STOCK LENGTH. The stock pushrod length is 7.794" correct? These say heat treated but does that mean hardened? I need hardened because I have guide plates. Also wondering what happens if the pushrods I replace mine with are a bit longer, like Comp part #7372-16 which ALSO say stock length, however they are 7.800" and 3x's the price.
