they are the same price... within like 50 bucks.. i paid 1000 for mine without springs brand new from TSP.. prcs..
no ls6 heads outflow the 5.3l heads... the 5.3l heads bump compression down just a LITTLE bit, nothing you will notice.. you will notice the difference though pof the lfow with that big of a cam.. one reason TSP talks the 5.3s up so much is that they make a LOT more money off selling those heads than they do sellng ls6 heads...... ls6 heads are better with an ms3 or 4..
i did 385/338 on a dyno that read about 20 low on hp and tq... that was no heads through a ported 90/90 410s 4000 stall...
i should pick up 40rwhp with the ls6 heads..

Stage 1.0 Ls6 outflow stage 2.5 5.3L? Not according to thier website. I think they are about 5cfm higher? Even with 5-6 cc smaller runners.
