Building a duratec for boost

So im wondering about what all I want to do to my focus next. Im already boosted and making good power but as many of you know, you always feel the need for more. At least I do. So my main focus, for now, is bottom end. Forged internals and arp hardware. Also clutch and lsd. So what I am curious about most is the top end. I've been searching for quite a while on building the head. I've thought about building my own with a 2.3 head but am leaning towards the massive head. But seeing as I have a 2010, im wondering about cams. I haven't seen much info on people who have actually installed the fi cams or any other info other than hard to tune for. Any input is appreciated.

I'd go for a 23 head w/ ss valves. I'd more then likey use the stock ones, for a turbo. What hp & torque are you putting down? A clutch & a torsen will do wonders.

I was at 210 whp and 190 tq at 7 psi. I'm now just under 10 psi but no dyno so not sure. It rides strong just want to up the boost and do it right.

How about doing a 23? It'd be pretty much the same cost, once you have a 23& you could recoup some of the cost by selling your 20.

I am currently waiting on massive speed system I purchased their ultimate head for my build but that is a lot of money to shell out, if your not going over 400 its really not needed.

Thought about doing the swap but not much luck finding one. I have a place that's local that has a bunch of the 2.0 for cheap so I could buy it and build over time. Still open to seeing as I haven't started yet

I want to be around 350ish. Like to see what that feels like and go from there. So basically im wondering what would need to be done top end wise to achieve that?

Of course. Stock bottom, from what I understand, is only good up to 250-260wtq. So would just bottom end be all I need to safely run the numbers I'm looking at?
