2011 camaro intake on a lq4
#6
243 Heads are Ls6 5.7L heads, also commonly found on 5.3L truck engines like the L33, there good heads but not with a Ls3 intake, wont work. If you want to use the Ls3 intake, DO it, but get some L92 heads on your 6.0 and you will make a lot more power then with a 6.0 243 combo for not much more money!!!

900 a set complete. 243s will be the cathedral port heads.
LS3 and L98 heads are the rectangle ports you could use with the LS3 intake which flows mighty well itself.
Those heads are the same except for the intake valve which is hollow sodium filled on the LS3 and solid on the L98. As i understand it some of the corvette LS3 heads also came as a very slightly more smooth casting for the runners but not a major difference.
