Obviously Green-Eggs know this inside out but another short clarification FWIW: ARP's so called "S65 bolts" are their ARP-625 bolts. These have a tad more clamping force, i.e. basically stronger/different metal alloy which in turn create more bore distortion. BE's bolts (also produced by ARP), have a tad less clamp force introducing less distortion (as well are a lower cost product).
From what we read the OEM bolts certainly does the job perfectly, BUT due to the procedure (turning 3 times incl last round with clock), it is fair to expect mistake to be made on their way in.
