They work very well on my car, which is a 202 LJ XU1 with a motor built by Ian Tate. You need to check if the fuel bowls are at 90deg to the throats before you decide on a manifold. I have a Lynx manifold originally intended for 1/3/4 carbs and it requires 15 degree bowls to suit, but using this manifold you gain plenty of clearance for battery and air filters  and also this manifold is somewhat longer than a GMH manifold which is helpful for better torque lower in the range if you are running a big cam like my motor has. My carbs are ex E Type Jag so probably similar to what you are looking at. Make sure you set up a choke arrangement to ALL 3 carbs otherwise you will never start the bugger.

Armours or Seton manifolds will suit the 2" SU.

Do you have a set already or just asking before you commit?
There are a few things to be mindful of.
Finding a set already on a Seton or Armours would be ideal, otherwise hard to find. Armours can be bought new still I think.
I looked at hogging out a lynx mani for a spare set that I had but I didn't think there was enough meat on it to be able to open it up to the full 2 inches to match.

Ian Tate supplied my Lynx manifold ported to suit. Seems to work quite well for me.

As others have said, seton manifold or armours are ideal- they work well on most wrm to hot 202s... the longer tubes give great torque with 2 inch SUs. 

 

I run triple 2 inch SUs from a jag on a seton manifold and they are very good. I ran webers for a few years and lets just say at this stage I am in no real hurry to re fit the webers- the SUs on the seton give great torque in the midrange (between 2500- 6500rpm they are excellent. Shorter manifold like a linx would do well also, but I havent run one so cant confirm categorically. 

 

I have a steel Seton prototype manifold hanging in my shed- one day ill give it a try... its longer than my cast seton... 

 

Most manifolds will need to be opened up a little to suit the 2 inch SUs... I think some CAIN manifolds may have been cast specifically to suit 2 inch SUs but theyre hard to find, and I think the cain is a little on the short side for most warm street 202s. They may be ok on a higher rpm application though.
