I think that your cam choice will be a perfect match for your converter and darn close with the gearing (I'd do 4.10's if it were me). I'm planning on something with around 224 intake duration for my LQ9, but with less exhaust duration since I'm running WCCH StageII 317's instead of L92's...I'll probably do 228 or 230 on the exhaust side (when the time comes that I can afford to fix my front and rear diffs, then afford to build the mill)

 

i got some brand new bare L92 heads if ure interested

 

I'm just curious what cams you think would be ideal then, for 6.0 ith either as cast l92 heads, or one with p&p'ed l92?
I've seen plenty of people come away happy with cams very similar to what the OP already has, but if you've got something better I'd be interested to see what.
