My ported LS3 intake pics/info
If you want to save your hands I used a different method for removing the posts on mine:
First i used a holesaw on the underside of the intake to cut out the bottom of the posts. Then my thought was to fish the robe saw in the throttle body opening, wrap one end around the highest part of the vertical support, then go to it like I am cutting sprinkler pipe. For the rearmost post I needed to add a length of wire to the handles of the ropesaw to allow it to reach.
It works like a friggen dream. It made a nice, smooth cut perfectly flush with the base the post attaches to! The only thing worse than ghetto fixes is when they work, and you have to endorse them and admit to them.
Here’s some proof:

that's sorta what I was thinking just hog it out from the bottom and cut it down as far as I can. I think I have some long shaft cutters at the shop that should reach deep enough to just hog the whole post outta there from below then plug the holes. Speaking of which what did you use to plug them hole saw holes?

Its amazing how much smaller the intake port runners on the intake are compared to the ports on the heads. I'm guessing that's where most of the gains will come from. But definitely not easy to do properly.
I havent taken my L92 intake off yet to compare the intake ports to the head ports but i sure will have a close look now thanks Hans
To the OP what grits of sandpaper did you use and bits for the dremel??? Thanks
Is it just me or does the inside of the intake on post #23 differ completely from the OPs pic of inside his??? ( I know that the OP sanded his )

Its kind of hard to tell from the OP's small pics. LS1 BU do you have bigger pics we can take a gander at?
Partick G tested two of them from a well known vendor, both lost power to the OEM intake. Texas speed also did two IIRC(its been a while), the first lost power to the OEM and I seem to recall it the 2nd gaining 5hp.
