what mm is that tb? im in the process of getting rid of the ls6 intake and going FAST..but which one im unsure of..thought the 102 might be too big but it seems to pull hard throughout the entire powerband

The nnbs style trucks already come with a 799 casting which is pretty much a ls2 head with the the bigger valve. So you take that big valve and cnc port then add a bigger cam you will lose alot of bottom end...... So knowing you have a 3.42 gear i would say dont do it, but if you change gear to like a 4.10 or 4.30 gear yes i would cnc my heads....
