I know alot of people are waiting for this block to hit the market. So am I Anyway, with these large cubic inch engines will we have to run a 2'' header because of the larger bore and big heads?

Large primary headers would be ideal for any LSx over 400ci. For the tall deck version of the block, you will need custom headers because the heads will sit higher, or you might be able to bend a set of normal ones, not sure.

Will the tall deck version of the block that sits higher (with the heads) clear the hood of a stock C5 vette and stock LS1 F-body?

Can't wait until these motors are being produced as readily as LS2 402 motors having been made the last year and a half!!
