6 Bolts per cylinder for the heads will greatly aid in clamping force as the LS motors are know to push water .

I thought the LS3 also had a 6 bolt head design. Isn't the LS3 block stronger then the LS2? The LSX block is also much heaver though, so why would you want the iron block if you were looking for 800 hp or so? Again I don't know so that's why I ask.
