Need opinions whether or not to build the engine

I thought since the mechanic will be doing a gallery gasket job might as well take off the valve covers and put in the exhaust cams in there. I think exhaust cams are a good supporting mod for boost while gaining some of the top end I lack of right now. Doing such would save me money in the long run if I ever go boosted while getting an immediate N/A gain although you guys are telling it won't be dramatic.

The car is a powersport toy for the most part. I want to be able to daily drive it if I buy a higher end car that will become the new fun car.

I thought one should have headers if going supercharger is the end goal which for me is yet to be determined but I would love to for sure. Also, exhaust cams and headers would work well together in my opinion since they allow more cfm.

There's another challenge to boosting my car since the only reputable VQ shop that can do a supercharger/turbo kit installation in my province strictly relies on Admin tuning and I kind of don't trust the copy paste work method he uses to tune for his customers.

I like N/A for this platform and I prefer not to boost my car for reliability reasons. I'm thinking more and more to save up for a final year ZL1 to have a factory race ready car.
