1) Morel's tick for a little bit anyway.
2) High lift with relatively short duration .050" HR's (especially with Roller Rockers) tick for a bit anyway.
3) Many aftermarket rocker covers are noiser.
Still, I prefer the multi weight. Flows a little faster when cool.
I have a 218/224 at .050" .570" lift HR (yeh, that's a little hard on the valvetrain) in my current small block. Hell yeah they tick for a bit...with multi weight...when cold. However, when 80+ out and water temp well into the 70's...it doesn't do it much at all.
PS: I run a plugged oil filter pad bypass too.
Warm up is crucial with these motors.
Black Baja's method/reason for changing oil types/weight is how I do things too. Without going overboard on weight. IE: going to a heavy straightweight.
Back to Darrin Morgan's saying: "Your motor is telling you what it want's, are you listening ?"

Something i think of substantial value that we can take from this thread is the importance of an oil temp gauge. Being from Ohio and boating in relatively cold water, I too, experienced long warmup times with my small block on my old boat. Before I installed the oil temp gauge I had a tendency to throttle up before I should have.
Pretty easy to tig a bung in the pan and watch the temp.

It's the hottest place. My stock Mercury pan has a bung in it for a temp sender. The only thing that might heat the oil after the pan is the oil pump. Everything after that is lines filter and cooler.

Hottest place, or that we care about, is at the bearings.
Next time I install bearings, I get some with a temp probe built in to them.
Oh boy, oil discussions always get fuked up. And then oil temp sender location discussions egt f*ked up some too.
Some like temp before the cooler, some after the cooler, some in the pan, and etc......

Yes sir.
Maybe some sensors on the underside of the pistons would be cool. Espcially for the SC and Turbocharged crowd.
Anyone smell burnt oil after a hard run ? This can sometimes be from an underisable tune and the pistons getting too hot. The oil splash that hits this area will then get superheated.
