My thoughts are as follows. First, if the pitting isn't severe it's probably OK to use them as they are. Second, if you choose to buy the new ones from NAPA, the extra length may or may not be an issue. Those of you with a ton of engine building experience correct me if I'm wrong but a pushrod .224" longer won't change the geometry of the pushrod/rocker assembly will it? A straight line drawn from the lifter cup to the rocker seat would still be straight even with the longer pushrod wouldn't it? On my '38 216 I have tons of adjustability at the rocker and could easily take a pushrod 1/8" longer. If the same holds true with the OP's 235 would it not be a case of just put them in and go? If I'm clear out in left field tell me so and I'll go to the corner & twiddle my thumbs but it makes sense to me.
