engine oil temp/noise

[tony69]

hello
what should the normal oil temp be on a new engine? my oil temp is about 240-260 deg. at idle. also i have a ticking sound comming from the vavle cavers. this engine is new with hydraulic roller lifters. its a 427 small block the lifters are from howards cam. ive tried to adust them but still the noise. do i have bad lifters from stock? what is the bleed down rate on hydraulic lifters. can't stand that ticking sound!
