[bimmerqc]

to make a long story short, I buy a bmw m3 3.2l 1999 (s52) surpercharge, I sold the kit S / C and install my turbo kit, I change the rod bearing, main bearing, piston ring and when I came to install my arp head stud I dislocate my cam and I saw the porting 6.5.4 of exhaust cam completely

The camshaft bearing journals are scored/scratched up from oil starvation or debris in the oil from a previous, messy repair.

The cam housing is replaceable, and I would do just that, replace it. The camshaft journals themselves can be polished & measured to see if they are still within outside diameter tolerance.

With the amount of effort you've put into preparing your engine already, it would be terrible to jeopardize it on two components that are available good used. If were mine, I'd replace both.
