[steveo3002]

i can find lots of info for braking in the cam on old tech american v8's , i have a 4 cly ohc vw engine does the same 20mins at 2k apply or not

schrick said nothing special needed try not to idle it alot , newman cams claims nothing needed ?

any thoughts

It depends on exactly what you've done, the history of it and the specification.
The more specific you are with your question, the more specific we can be with an answer. Right now we're at level one; vague.

Is it just a like for like cam swap or not? What happened to cause this job to be done?

[steveo3002]

very low miles head , decided i want a high lift /performance cam , so got one with new tappets

just wanted to know about break in really...like i say theres pages about push rod v8 but wasnt sure it applied to my engine , cam sellers vague

If it's just a cam swap for performance then there isn't much of a procedure for an OHC. Throw some fully synth in it (and on the cams) and ride off into the sunset if you can, it won't need an oil change if that is all that was done. There isn't much in the way of bedding in (unlike new cylinder bores) which leaves metal in the oil.
The only problem I can see is your engine won't run properly if the cam spec has changed so you won't be able to do the above. You will have checked piston to valve clearance?
There may be some break in guidance on Kent and Pipers sites too, but there isn't much to do or go wrong really.

[steveo3002]

kent and piper suggest the 20mins or so at over 2k

yeah the cam should run okay , no piston mods required etc plenty of folk run them on the owners forum , just want to do it right

[stevieturbo]

Number of cylinders irrelevant...and OHC can cover a range of configurations of valvetrain operation.

But if the cam suppliers are stating nothing needed for your specific application, then there probably isnt.

I'd suggest, over 2K as above, not more than 3.5K, but vary the speed, in case that are hamonics that impede oil flow at certain rates. You don't want the new caams drying out.
