IH 574 exhaust manifold problems

Hello. I own an IH 574. Got it at auction five years ago and
have had to basically replace everything on it. Carb,
distributor, wires, plugs, (most) fuel lines, fuel pump,
sediment brown (was silicone shut), and the belt. It runs but
this year Im having trouble with it over heating and back
firing.

I knew the exhaust manifold was cracked but it seems like
the intake is going as well. Its beyond repair. So I have to
get a new manifold.

Problem is I just happen to have the under slung version of
this tractor that is apparently very rare. So there are no new
manifolds available and used look just about as ratty as the
one Ive got. Also they want $400 for it as opposed to a new
overhead for $150.

I was wondering if there is any issues with just slapping on a
brand new overhead exhaust/intake manifold and calling it a
day. I might have to cut a hole in the hood but I have the
equipment to do that.
 
Try bates corp, look them up on the net. All they do is IH tractors and they do have some nos stuff also. I have gotten stuff for tractors that I couldnt find any were else. Good luck!
 
Lots of things can cause over heating. Timing,plugged radiator inside or outside, loose belt over working, low coolant level. so there are some possibilities. As for the manifold Try these places for one. J.P.Tractor Salvage in Fredricktown MO,Bates corp in Bourbon IN, Worthington Ag Parts, And All State Ag Parts. I've dealt with all of them with favorable experience in the past. Though I do think Both Bates and Steiners are high for their parts.
 
Same problem with bates. Its not in stock and even if it was it would be used and $450.

I know the manifold is bad so even if that doesnt solve the cooling issue it still has to be done. There is a visible hole in it that I have just a temporary patch on.
Bates manifold for the 574
 
If youre ok with cutting a hole in the hood, thats cool. But if you really like that down swept pipe, separate the manifolds and make a new exhaust. Its easy.
