note that the 1uz vvti buckets whilst SUB are still only 31mm dia and thus still pose a limit for nasty cam profiles. 33mm shimless would be a nice upgrade. having the OS valves with 5.5mm stems is a weight bonus too, especially nice for RPM gain. ufortunately this is offset against the shockingly bad rods warranting a bottom end rebuild none the less
