I used a hammer and chisel. Worked great. Won't hurt the manifold. Just whack 'em off ... so to speak.
Nothing more silly, IMO, than wasting money on the later style coolant tube set-up. Completely unnecessary.

The LS6 intake don't use the return to the rear, .The fitting on the rear are blocked off and the front is only a cross over pipe. The tube the goes from the front to the rear is deleted.You can get them from a GM dealer =

just knock em all off raymond... I just did this over the weekend and it wasn't too bad despite me ripping my skin when I try to loosen/tighten the back bolts on the manifold. Click my screen name and look for my thread. Make sure you are very careful removing the intake/replacing with the booster hose since the oil sensor unit is in the way.

I just cut mine off after the Y in the front, and left nubs on the two back connections. Then I busted out the good 'ole JB Weld, filled the openings where I cut them off and crimped them. No leaks and it does the job with only $4 invested into the stick of JB Weld.
