Any plans for edelbrock or someone on these heads? Is porting stock heads the only option at this point?

Exactly....it's not necessary at this point, as most engines aren't even making the most of the stock head.

I'm considering a turbo with a modern hemi in a 71 cuda race car. Not sure ported will be enough. I'm thinking I need to talk to someone who has done this. 3200 pound car to run 8.50

Can the block and other 3G Hemi stuff out there take the HP and TQ to go 8.50's with 3200 lbs?

Talk to Tim at www.mrnormsgarage.com he has a twin-turbo 09 Challenger that runs in the 8's and soon to be in the 7's. 
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

I see LS engines get close need a mopar to show them up. Very risky on the block but some hard block should help.
How much power are you going for the 3rd Gen Hemi have made 700HP NA. The LS engine have there limits must don't uses stock blocks they use the LSX block the stock ALum block can't handle much power the the LQ "stock Iron truck block" has its limits too. We do have a Alum. block out for the 3rd gen hemi if the stock block can't handle your goals and the new apache head is a great head and guys are just starting to dig into it.

I haven't heard anything yet. but the 3Gen hemi's are a great head to start from. Anything that would be a improvment would be a race head only.
From the 5.7 eagle head to the 6.4 Apache head I been seeing flow numbers from 280-300+cfm in a stock head with porting even more so.
And they are super cheap on top of that the after market would be very hard press IMO to top the stock head IMO
 when the 5.7 came out, David Vizard did a big article on them, and with minor bowl blending, he got low to mid lift flows better than a SB2 NASCAR head, with max flow at about 300CFM...with the stock 1.9 valve. now toss the 6.1, 5.7 Eagle, and 6.4 Apache head in the mix, and you have a factory casting installed in vehicles that OOTB are approaching W7,8& 9 as cast flow capacity, or bettering max ported W2's, W5's and Indy small block heads....
