Just an FYI - there are four 6x20 bolts that go on the front of the valve cover (P/N 93500-06020-0A ) and their Allen heads are too tall to allow the tappet caps to be screwed in properly. You'll have to get four flat-head replacements to obtain adequate clearance. Found this out yesterday after spending an hour sorting the bolts out and torquing them down.
Otherwise the alloyboltz kit (from ebay) seems to be a quality product and even includes instructions for properly torquing ss bolts with anti-sieze. The 6mm bolts have a "wet" torque value of 4.4 ft/lbs as opposed to the ~5.6 ft/lbs listed in the manual. The torque wrench I'm using is in inch-pounds though, so that's 52.8 in/lbs.
