4A-G DIYPNP

good choice on the DIYPNP - will let you know in a month or so when I finished assembling it... personally I went for it due to the neat look and ready available addons to allow it for sequential fueling and ignition (although I'm going wasted there). Regarding the +EM rods you'll have to check with Jeff on the schedule - I know he received two sets so far - only one available to the public but he should get a big bunch (-1 for me) sometime early next year.

regarding the ARP bolt it boils down to the following the smallest area they maintain for oilflow is bigger than the smallest area the oil has to go through in the head but clearance around the stem of the stud is half that of OEM bolts (in numbers just 0.55mm for the ARPs)
