F-model Rod Bolts

Tore into an old bottom end laying around the shop to start building an 836 for this spring (yeah I know it's already spring, that's why I gotta hurry).  Found something that'll save me 50 bucks and some time.  At one point in this engine's life someone who knew what they were doing was inside this engine.  I found that the crank has been cleaned before and allen screws installed to cap the oil passages.  I also found it was already running F-model rod bolts on K rods.  The original K bolts (seen on the left) were "torque to yield" and have to be thrown out when you remove the rods.  F bolts are reusable and also cheap insurance against the weak K bolts in the budget 836 I'm building.
