Cams Break in procedure?
So im about to do my cosworth Mx1 cam install. I opened up the Box to find a Piece of paper with the cams specs as well as a break in procedure and recommendations.
On the paper it states
"-New camshafts MUST always be cleaned throughly, deburred, and blown with compressed air before use"
i looked up deburred and found deburring - Removing burrs, sharp edges, or fins from metal parts by filing, grinding, or tumbling in a media that removes the burrs from the aluminum.
sorry if this is a newb question but do we need to deburr it ourselves or should this already have been done by cosworth? I looked at my cams and they do seem a little rough.
Also my mechanic reccommends we use non synthetic oil for 50 miles part of the break in procedure then change out the oil to synthetic after the 50 mile break in period..did anyone else do this?
This is kind of new for me because when I did my cams on my 8 it was just a drop in, tune and go.
so any tips would be apprettiated

I think they state that to cover there own a**, just in case a bur falls off during operation and blows your motor; they can say it should have been deburred and inspected before installing.

apparently theres been many installs especially by shops but i doubt there gonna chime in idk if its a bussiness killer but understandable
im not bashing the product dont get me wrong, I just think its kind of bull crap if they do need to be deburred whats the point of paying almost $800 for cams that may or may not be ready to install? Like i said my hks cams (280s) just plugged right in.
To be honset if I knew these cams had this procedure in it then i would have just went with Kelfords...

I dropped them in without even looking at them, I agree with sk8terdude929, they probably wrote that just to cover their own a$$ if any damage is caused by some bur. Maybe in the past something like that happened to them so they decided to thrown that line into the instuctions.

Deburring is a pretty simple thing. You use emery cloth, or a small mill file, and look for any rough or sharp edges on the corners of the machined surfaces. NOT THE MACHINED LIFT SURFACES!
Then you take them off. Same for the face where the gears mount. The manufacturer does do this prior to shipping, but, if they miss something, you are screwed. It is really a small thing, and very easy to do.
Cams need to be broken in. On some, like old school v8's, you would run the car at about 2500 rpm continuously, with a bit of up and down, for about 20 minutes, prior to driving the car. You would also have assembly lube on the cam lobes, but I don't know if the same process works for this engine.
I would call Cosworth and ask them how they wnat their cam broken in, and then do what they say. I am sure it is a variation of the same procedure, possibly without assembly lube.
