Default PP Stage 2 or Stage 3 heads for Turbo app?

Hey guys... ok what do you think... I am buying some PP heads with 68cc chambers. But do you think I should go with?

2.02"/1.57"

2.055"/1.57"

2.08"/1.60"

I have heard of people having problem building boost if the heads are too open... what are your thoughts as to which size and why???

Thanks!

Jared

I would think all would work, but you are running a 408ci right? I would go with the Stage 3's. In theory you will make more power with less boost.
