PM me for a dealer website that is selling brand new GM LS6 heads with hollow intake valves and sodium filled exhaust, ls6 springs and locks/seals installed. FOR LESS THAN $490 each. They even have free shipping on orders over $199 ! All genuine GM parts.
I just came across them yesterday in my search for parts.
EDIT: ADD
GM LS6 heads are $473.09ea. The true LS6 with hollow stem intake and sodium filled exhaust valves!
GM part#12564824

Car craft February of 2009 had a article on the LS6 (243) heads and told the difference in the casting procedures that had 2 seperate casting plants and Ican't remember where I seen that the ones that had the A right below the spark plug whole where worth around 6 to 10 HP or something like that, I don't remember where I read that but hope this helps.

Try to find a set of 243's with Triangles cast in the head .
They say this is worth an additional 10 H.P.
Have them stage 2 cnc ported by TEA Total engine airflow. You cant go wrong.

True ls6 heads Do NOT have titanium retainers, I recently swapped valve springs on a set I bought years ago when they were more plentiful. The retainers are exactly the same as all other ls heads....
