4 Corner Water/Steam Ports

[Foggy]

Looking to see if anyone has successfully found a decent 4 corner steam port system
that will fit under the stock 6.2 intake manifold.
I found one with flexible hoses, but it comes direct from china and I don't trust crap like
that I find on facebook.
TIA

dorman is the only one that even makes a replacement anymore the oem one is oop
the rear is usually just capped off
are you getting high temps or something? if so hollow out that 3rd cat, seemed to help for me
if that trans cooler is in front of the radiator move it under the bumper

I just really like the idea of the 4 corner system.. I know it's not mandatory for the
trucks/suvs as the engine 'angle' is more favorable than in the cars... But I'd still like to
use it !
I can always use some cooling help in the summer while towing !!!!! I've got
the best cooling setup, but trying to be pro active. I saw a 4 corner system advertised
on fakebook, but I don't trust the chynesium stuff at all

All 4 port kits you could ever want.

How do you like your LT1VVT cam?

There out there I haven't looked in a long time, should be some around for the ls7, etc which should be the same size

I like it. I wanted to keep vvt and not change all that stuff out. So that's the
main reason.. And I knew I wanted just 1 step over stock cam due to towing and
wanting to keep low end. Still have low end... but really starts pulling hard over
stock cam in midrange. Needs tuning for sure due to more duration and tighter LSA

Oh. No Tune yet?
I have the same cam in a rebuild that's not installed yet.

I've tuned it with HPT.. but I'm a rookie, so it's still a work in progress.
It runs well and mph is good so I just haven't gotten too worried about it.
I really only drive it about 4-6 K miles a year

I have to learn to tune mine once i get it installed in a few more weeks.

Does the factory one from the first few years of GMT800 not fit under a 6.2 manifold?

Installed this 3 years ago. Ive taken it off and on once since and found no issues. The only suggestion is to place a small bead of rtv around the o ring and bolt it in loosely overnight, then torque it in the morning.
without doing that you will need to get it warm a few times and then re-torque with the intake in place. not exactly the easiest but can be done.

The steam ports in the back are only needed if the engine angle is less than 3 degrees down slope, they do nothing if the drive train is angled down to the rear

They also don't prevent overheating, they just prevent hot spots in the combustion chamber due to air pockets where coolant must be; your temp gauge won't show these hot spots because the coolant at the sensor isn't too hot, but your head will crack eventually above the cylinders that trap air in pockets in the combustion chamber
