I used thin brass tubing on my Ford 3X2 intake.
This pic you can just see the top of the tube.
Sorry I don't have any better ones.


I think I had to sleeve 4 in total where the porting broke thru.
These were a very tight fit.
I had to ream some of the holes to get the tubes in.
Not a "thumb push fit", I made a driver tool and tapped them in with JB Weld on all surfaces.
I'm not worried about them leaking.

Every 20 minute job is 1 broken bolt away from becoming a 3 day ordeal.

Since those tubes were only epoxied on the ends, I would revise my advice and say clean up the pushrod holes like I mentioned above, clean the tubes you have, roughen up the outside of each tube and coat them and the pushrod holes completely and push them back in.  The extra epoxy should insulate the tubes and aluminum enough to keep them locked in place indefinitely if done correctly.  Someone did not do you any favors with only putting epoxy on the ends.  If there are pin holes in the intake ports where the tube area was weakened, any excess epoxy from the inside the pushrod hole should seal it off if you twist the tubes as they are inserted.  Joe-JDC

The old tubes are scrap metal now. Where the porting broke through is more like a thick line on both sides of the port. While i was driving some of the tubes out there was traces of oil that ran into the port. Aluminum tubes are ordered.

if you could tig weld the bottom and top of the tubes that might help keep them from leaking again

    Just an update intake is back on. New aluminum tubes installed and epoxied. It was quite a bit of work removing steel tubes. Dremeling old epoxy off, I had to ream all the holes. Car seems to run well. The idle adjustment is completely different. When the salt on the road disappears, I will take it for a ride. Thanks for the expert input. Now onto the emergency brake issue.

I found splash zone and a bunch of JB weld. Is this the right JB weld? looks like splash zone is 80 bucks for a quart. JB weld 8.99  I am not worried about the price at this point just getting the right stuff.

That JB weld will work just fine
