Is it necessary to re-degree camshafts after changing cylinder heads?

Is it necessary to re-degree camshafts after changing cylinder heads?
So I am swapping a new head on to my motor. It’s the same head as before just got it resurfaced and put a new valvetrain in. I am still going to use the same cams. Would I still have to degree the cams once everything is installed?

Re: Degreeing Cams
How much was taken off of the head?
probably not worth worrying about it it was just a "resurface until it cleans up" kind of job. I'm assuming it was just "flattened up" not "milled" to significantly increase compression.

It was not milled still oem size. I just had the the face resurfaced. I have type r cams which were in my other head. My old b16 head cracked so I got another one w and put all supertech valvetrain. So I’m curious to if these cams would even need to be degreed. Thanks.

If that's the case. The SAFE course is to actually degree them. But since they are an OEM ITR, it's more than likely not necessary, unless the pistons have changed. But again, if you can, take the safer route.

Re: Is it necessary to re-degree camshafts after changing cylinder heads?
In your particular situation, nothing really, unless (again) you've changed an area that would greatly vary your Piston-to-Valve clearances, like pistons or flat-top valves. Since it is an OEM camshaft, degreeing really isn't that necessary, even with a Type R. They're special, but not that special.
But I'm overly conservative. If you have the means, equipment and know-how, sure. But for an OEM cam, meh.. not all that necessary. But I'm just telling you my perspective from my experience, nothing more. I can't tell you what you should or shouldn't do.. I can only suggest based upon the information you reveal to us.
