l92's on a lq4

[68GMCCustom]

hey you're always saying that the L92/LS3 headed cars/trucks can't hang with a good cathedral port one! Just thought I'd give you a shot at mine when its ready.

Well the way I look at it.....the GM engineers must know what they're doing to bring us these fantastic motors in the 1st place right? And, since the factory is building 6.0L motors with the new genIV L92/LS3 style rectangular port heads (LY6, L76, etc)...they must not think that a 6.0L's bore is too small (or shrouds the valve too much) for the rectangular port genIV heads?

As far as the swap...only the intake rockers are different, but the exhaust have the same rockers as a catherdral port head. And you're right, no..........the big port heads aren't for everyone.
