427supr: Welcome back! Glad to see you decided on the 408 - good choice. Like the guys above, I would suggest you sell the GT40 heads and go with an aftermarket brand. The Vic Jr's are a nice choice, but if you really want the 408 to sing then I would go with the AFR 205's.
If you're going to go through all this work, don't restrict the engines ability by re-using the stock heads. I know a few guys that changed their GT40 heads on their 392 crate engines to AFR's and they picked up 70-90 HP. -That's how restrictive the stock heads are.

-Spend a few extra bucks and do it right.
