I did not port the heads myself I bought this rig they put custom headers built with 1 5/8 tube

[Paulbean00]

Also it's 2 inner header pipes on driver side

Just the drivers side or both? If just one side i wonder if you have two fuel pressure regulators one on each fuel rail or just one. Its not real common for a fuel rail to get plugged up but one can starve for fuel if the fittings are two small or a regulators is not feeding enough fuel.

Sorry i got nothing but questions.

Swap injectors and eliminate them from the trouble shooting.

It's just the driver side I checked intake bolts and one side was loose and the other side was kinda loose I tighten them up and then did compression test all of them have good compression. I'm about to see if the intake being loose was the problem I'm waiting on battery to charge lol if it ain't one thing it's another

[Paulbean00]

I'm also gonna check the injectors as soon as I get a good idle

[Paulbean00]

It's number 5 and 6 that are glowing 1 on each side. I start the engine and within 2 minutes there glowing red

If you have a miss fire down a pipe its a rich mixture (Because it didn't fire in the cylinder)and will be audible when firing in the pipe a lean cylinder will fire hotter and a very hot blue flame will be right at the exhaust port and as rpm increases that hot spot moves further down the pipe!

heat in the exhaust is actually good, and creates better scavenging in the pipes, wrapped headers hold heat and create horse power! A lean burn in a cylinder creates excessive heat and causes piston and cylinder damage! My headers are cherry at night or dusk but aren't that noticed in the day or under lights and there is no problems with my engines! A Higher octane fuel can help! Are you running pump gas?

The cylinder heat, if too extreme running lean will usually cause an early ignition from hot spots like a hot exhaust valve and you havn't mentioned that! From what I read your only worry is 2 pipes glowing more then the others?

I'm running super unleaded from pump gas the glowing concerns me but also it's back firing thru the intake and it won't idle

[painted jester]

You can drop the exhaust at the collectors and see if they still run hot, hotter, or if they look normal? It could just be too slow scavenging pipes you said they were custom fabricated so you have no Idea what hind of quality pipe fitting was done inside those pipes? A little bit of metal in the pipes or a weld wall can deflect the exhaust flame towards the tube and not straight creating a very hot area that will glow! Too quick of a bend right at the flange can also create a hot area where the flame is directed to the tube wall before making its curve down the tube.

Post a picture of the exhaust glowing and let us see the header design.

Sounds like intake valves too tight or not seating! Set your lifters at 0 lash if hydr. for a running test and if it cures the back fire reset them to specs when hot! Check em hot if solid!

Week springs can cause the same thing! Or a timing issue! You need to take care of these issues and then worry about the exhaust

Another vote for checking the valve lash and firing order. When you get it where it will idle your glowing pipes will pobably go away.

Does the exhuast have cats are thye plugged. I am assuming not if its a rock crawler but you never no with racing classes these days.

Plug cats can have all kinds of issues.

[Paulbean00]

It has glass pack and flow master 2 mufflers off each header

I'm trying to post pics
