2013 vxr small hairline cracks in motor head

Hello. New to the pwc world. I bought a used 2013 yamaha vxr 1812 cc. 38 hours. Looking to get an opinion on any possible problems. Ski runs fine now. I hit 70mph last weekend. But has a louder deep engine sound than normal when I first took it out. I've put 6 hours on it since. I recently saw what looks to be oil coming out between header and manifold. I think it needs new gasket. Also I noticed a couple minor cracks in header under the removable plastic top. But not leaking water. I added a couple pics. Let me know if this is serious and what, if anything is to be done. Thanks in advance

Honestly, all I see are casting flaws. What you are calling the header, appears to be the valve cover. A header is either the exhaust manifold, or a aftermarket part that replaces the exhaust manifold.
If the valve cover gasket is leaking, by all means, replace it.

Thank you Rodsatheart. That make sense. I'll monitor the oil leak. Gasket replacement seem like an easy enough task. Am just to un-bolt the valve cover and slide off old gasket with new one? Any idea what part number it is and best place to get one? Thanks.
