Get them while you can, cause like other rare Corvette motors the parts will only get harder to find. Just my opinion....

It's a pretty substantial increase stock vs stock
Just for comparison the LS1 heads flow 252CFM @.600 lift...so stock they flow very similar peak numbers to the LT4 heads

Dont get me wrong, but the power difference isnt worth the money right NOW for LT4 stuff. You can pretty goodpower IMHO with LT1 stuff.
And AFR is supposed to be making a new cylinder head that uses allot of LS1 technology in it, for comparible flow numbers and are to be out this year. But then again........
