I'm sure others will chime in but from what I have been told...if you are only planning that much boost and conservative hp, the stock heads will be more than enough. The cam looks a little on the big side. My cam is considered pretty aggressive and it is a 224/230 .581/.588 114 Yours is even bigger than that. Probably going to need some different valve springs also. I was told the Patriot Gold Duals are nice. That was what I got.
Hopefully, some others will chime in. I am also in the process of doing my first build so take my information with a grain of salt.

[QUOTE=pwrtrip75;15640298]Leave stock heads, works way better and you shouldnt have an issue. I'd skip all the ARP stuff too... that turbo wont make enough power ghs around

I went with that theory too.....Except mine broke both prematurely on one valve (inners only on 3 others)....didn't fully drop a valvle though (but you could push it down easily with your palm). Enough where it left a mark on a piston.
seems like a really close setup to mine
Im doing a 5.3 with a stock bottom end with 241 heads for some lower compression
as far as cam choice im going with the LS9 cam to keep cost down low
