COMP Shaft Rockers for LS

The valve/rocker geometry between LS and GenV LT engines is different, right? I thought I remember hearing the exhaust is the same, but the intake is a bit different?

The rockers on an LT engine are like LS7 rockers (1.8 ratio). But the intake rocker mount in the head is offset/twisted. So the rockers are not inline like the LS heads are.

Ah, thanks. That sounds about what I heard.

Would be sweet to be able to have a shaft system for the GenV's.

LT heads are 12.5° / Splayed 2.61° & 12.0° / Splayed 2.38°
Jesel is the only one I know of that has made 1.9 rockers for the LT heads.
