Im wanting to do a lq9 short block with l92 heads just curious on the cost of the heads and what all will swap over from my 5.7. As far as heads i have heard the springs and valve covers still work, the rockers and pedistools are different

 

About $430ea (new) for L92s, $350ea (new) for LS3s. 1 valve cover will need to be clearanced for the new rockers, only the intake rockers are different, exhaust rockers and pedestals are the same.
