what oil to break in new cam heads?
Do I use conventional oil instead of full syn to break in new heads/ cam? And do I use assembly lube on the cam bearings? My first ls build....lol

There is no specific break in oil for a heads cam swap. We always coat the cam in oil before it goes in the motor. For break in all you need to do is make sure the springs get heat cycled once or twice. We don't use synthetic oils on these motors, we prefer a standard oil because it provides better lubrication for these types of motors.

yeah no assembly lube on the cam,just regular motor oil on it before you put it in.I laugh when i see roller cams going into motors with all kinds of red assembly lube.All that crap does is stick inside your motor

I am sorry my wording was incorrect. We prefer standard oils, especially for break-in periods, over synthetic oil because it allows the motor to wear in correctly. Synthetic oils actually provide so much lubrication that brand new motors will not see the correct type of wear to break in properly. For this reason we recommend using regular oils until at least a few thousand miles are put on a new motor.

Mobil 1, for example, claims on its website that engine break in works just fine on synthetic oil.
[ of course, it is not cost effective since it will be thrown away in a very short number of miles ]

That is true, but like I said WE prefer to use non synthetic oils for brand new motors. If GM chooses to use synthetic oils on their brand new motors that is their choice. We are just trying to make sure the motors we provide are broken in correctly so they run at their best. Just because GM does something does that make it right?

I can see both sides of this argument but GM is wanting their engines to last well past 100,xxx miles I would guess. I would think they would do something a little differently if it would help with engine longevity.
And no, just because GM does something it doesn't make it right.
They put a 7.5 10 bolt in our cars and we all know that ain't right.

current oils don't have the good stuff in them any more ,removed to help with cat life.there are some oils designed for break in(comp cam),mostly concerning flat tappet use.I was told valvoline racing oil is good for break in also.

I still think that if dino oil was better car manufacturers would use them. I thought I read something once with roller cams and the way cylinder walls are finished now that synthetic works fine.
It's amazing to me that even now you can't get a explanation of why you should or shouldn't. I mean yeah there are opinions but I am talking about actual facts.
Maybe we need to get Shane on this to kill another internet myth.

I agree with you though. The only reason I would use a dino oil for break on a new motor (not just heads/cam) is because it will have to be changed sooner. Its cheaper than dumping out expensive synthetic oil just for break in.
