Go with a 48* w9 head and run a offset rocker like you have with the Indy. Then If you grow again you can get matching block.

Best? That's extremely subjective... What are your goals? I run Eddy RPMs, but I'd go to W9's if I had the coin.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.

You have the 360-1 but someone went too far with the ports.. thats not the fault of the heads... they would be my choice again but less porting... a standard CNC port job would be it.. your running boost, if you want more, just turn it up... that way all your parts will work.. going to a W-9 will cost you big time.. every thing from the head, rockers, lifters, pushrods, intake valley, intake and custom headers... thats gonna cost.. its not even cheap if you build most of the stuff yourself.... good luck with it

Keep in mind that the biggest thing with boost or the sauce, is that what goes in must come out. I would think exhaust flow numbers would be more important.  Matt

Thats very very true... its easier to put more pressure
to the intake side but it still has to get out.. depending
on what style of pressure it is(turbo or blower) they
dont need the collector.. get it out as fast as possible

Its a procharged set-up. I'm leaning towards another set of Indy's at the moment, but that could change.
I know INDY had a great exhaust on the first run of CNC heads. They flowed 245 and up.
I THINK they changed it due to them breaking into the water jacket.
IMO INDY has a good design but a questionable product. IF you going to purchase a set, get them through a dealer have them checked out and I mean check everything.

Stay away from the 245 heads, the 230 seem to have less problems.

Figure out how much power you want to make and how much RPM you want to turn.
My Stock ported iron '308 heads with a sub .500" lift cam made ~725hp at only 240~250cfm flow.
The boost will make power on just about anything... no need to get carried away on the heads.
I just got a set of eddy for mine (to replace the cracked iron heads). They flow 290~300cfm with the MCH CNC port job. That is more then enough for the Chevy guys to make over 1000hp on a 80mm turbo. So no reason why a mopar can't do it either.
How much power do you want to make? How big of a blower/turbo? How much RPM? How much CID?
Same questions for a N/A motor still apply for boost.
I think he has far exceeded that already

Not saying that he doesn't can't make more...just making a point that flow isn't as important on a boosted car like n/a
