Default Mast cathedral port 245 heads+370ci+F1R+E85?

Really thinking hard about switching from the WCCH 317's to these heads, Any thoughts on these with 370c.i. + F1R + E85 and as much boost as she'll take?

at some point this winter (before spring) I want to put some "decent" thicker casting heads on the car... No hurry, just looking now, but this will be done before the weather gets warm. I just put new exhaust on the car, custom 2in primary headers, and 3in all the way back. So buying FULL exhaust twice for the car wasn't fun, but you know back in 2005 1 3/4in primaries and 2.5in exhaust was all the rage!!!

I know you just bought that bad *** billet intake manifold, but if you hadn't I'd recommend you get their 12 deg LS7 heads!!!!
