V6 oil issue

So I have a G8 with about 90k miles and it appears the oil was not changed regularly and there is quite a bit of build up by cap. I am running some seafoam in it today and changing oil tomorrow to try and break down the oil build up, so here is my question. Would you suggest doing an engine flush (put a detergent in for 5 minutes with a new filter, and drain, change filter and new oil after that) to clean the engine better or do you suggestion something else? Maybe run next oil for 1000 miles and run seafoam in it longer right before I change it? Any suggestions would be great.

- I am planning on putting in a mobil1 or castrol 5-30 full synthetic, sounds like prior it had run Amsoil
