Stock rods are pretty darn good for rpms within the range of your intended use. I have a friend (cstreit) who's been using stock rods in his 250 WHP 3.3L N/A since 2005 and they've served him well. Actually had one failure but i'm not sure that's necessarily a rod issue. Spun a rod bearing which then did ruin the big end of the rod.

Pauter rods are nice (I have some) but for your type of use they don't really gain you anything. They're not massively lighter than stock rods and you don't necessarily need the added strength from them.
