The two ends (which are for cylinder 1 and 6) on the exhaust manifold do come off, but they shouldn't fall off.

Find your correct year and click on the number for parts
Someone might have some they are willing to sell. Those are kinda pricy

Congrats from a fellow newbie! Are you and Fido gonna have to live in the Cruiser for awhile?
No problem!
The ends should have some free play. You could check if your seals are okay. Not sure how to do that though.
Each end of the exhaust manifold has a couple of ring seals (like piston rings) and some wave washers. You can purchase these parts from Toyota, or from SOR, and some of the other advertising vendors may have these, although it seems like it's a toyota-specific part.
The recommended intake/exhaust manifold gasket set, by the way, is a set from FelPro. Do a search in this forum and you might even find the part number. It comes with the manifold to head gasket as well as the gaskets that go between the intake and exhaust manifolds (heat riser gasket).

thanks for the help guys we got the parts today and installed the intake and exhaust tomorrow were going to tackle the carb again. what is the purpose of the insulater between the intake and exhaust. and living in south ga is there any need for the "flapper" in the exhaust i hope not cause it is now gone.
I'm hoping you checked the manifolds with a straightedge before installing - they have a tendency to warp.
Buddy Sue;4028753what is the purpose of the insulater between the intake and exhaust. and living in south ga is there any need for the "flapper" in the exhaust i hope not cause it is now gone.[/QUOTE said:The heat control valve is open when the engine is cold to the the hot exhaust gases up next to the intake. This helps preheat the incoming air and vaporize the fuel. The valve closes when the engine heats up to divert the exhaust gases away from the intake. You are probably OK without the valve. Just make sure you plug up the shaft holes.
careful now...
when the heat-riser flap is removed or burnt it allows hot exhaust gas to blast against the bottom of the aluminium intake manifold, often cracking it, the owner of SOR diagnosed this on my truck just by listening to it, it's a common problem. SOR sells stainless steel insulators that fit between the intake and exhaust to protect the intake. I don't know if it will protect it enough with the flap gone, but I'd guess it would. Or just get a new header and consider it your trucks christmas present for the next decade
The crack in mine was visible on the bottom of the intake and in the top under the carb.
