ls6 intake install ?'s
ls6 intake install ?'s hey guys i've searched, and didnt find much, and i'm going off ls1howto.com to do the install, my question is i noticed that if the intake is the non egr version you have to do away with all that obviously, i have the coolant pipe but i dont think i have the plugs not sure what they look like 
ill try to post pics of the parts i have. and as far as removing that goes, when you take the egr hookup off the pass side headers ( i have hooker LT ) it says you need a block off plate, what would this look like ??? i just want to do it right and not be in the middle of it and find out i am missing something thanks for your time on a pretty basic question guys.

the plugs look like whats on the tube that you connect to the front of the heads except they are not hooked to the tube. they are just single plugs. the egr plug is just a piece of metal that is cut to fit and bolt over the egr hole on the header. i grabbed a piece of aluminum traced the outline of the egr gasket and cut it out and drilled the holes to match.

You'll need the coolant plugs for the rear (think there's a pic on SLP's site). My buddy got them from the dealer when we did his. You also need the EGR block off plate for the pass side header - you can buy one or trace it and make your own, looks like the air tube gaskets (w/o the hole) only slightly larger.
alright i guess i just didnt see the coolant plugs in the bag when it was sent i got to looking and saw them. i got the intake off here, is there any serial # etc that i can check to see if it's the actual ls6 intake? so all i need is the block off plate, would a GM dealer sell them or would i have to make some / order some aftermarket? thanks guys.
Your hooker LTs didn't come with a EGR Block off plate? If not, they're not hard to make (I made my air tube block-off plates out of an old liscense plate). Or, you can order it from a sponsor-they're cheap. Dealership won't have it.

From what I can remember about this mod (it's been awhile) all of the "LS6" intakes are flat bottom. Is yours? That was pretty much a telltale about the intakes. Make sure you have an F-body intake and not a Vette intake, though. There are no TB provisions for an F-body application on a Vette intake.
well i bought mine already from a guy on the board named timmy2stage, came with the coolant plugs and all. 
i'm sure ill notice a difference when i get it off on the bottom i suppose, he had it on a camaro so not worried about it not fitting so much just wanted to " double check " and make sure it was a ls6 intake though thats why i asked, not to be rude to tim, but just for peace of mind

I have a big *** piece of stainless steel plate behind my house that's about 16 guage or so. I have cut 4 different block off plates for people from it. You can use the gasket as a template, trace it, cut it out, then drill for the bolt holes.
I made a whole set for my AIR/EGR on my manifolds before i got headers, and i made one the other day for my buddies cobra. I used a die grinder with a cutoff wheel, then used a stone wheel to smooth out the edges, then a wire wheel, which leaves a nice polished finish.
I would NOT recommend using the LS1 coolant pipe. It will go on and seem like it fits fine, but it will have the fragile intake in a bind somehow and possibly crack it, or not seal properly. Go to the stealership if you have to, tell them to pull up the coolant pipes from a 2002 SS or somthing, then look at the screen and point out to the dumb asses which parts you need, i've done this **** countless times. The proper front pipe, curves out to clear the bottom of the intake manifold, and the rear "plugs" look just like the ends of the pipe, but they are just blanks with no holes, and no pipe coming out.

you have it backwards. the LS1 style 97-00 are rounded in the center and the 01+ are flat all the way across. that is why it is hard to make the coolant lines fit (LS1 ones) on the LS6 intake.
