Ok well i bought a 96 12 valve engine that was pulled from a truck and to my surprise while stripping, cleaning and replacing gaskets i found the one exhuast ports on the head was cracked and fell of when i took off the manifold. Is it fixable or time for a new head?If so where would a good place be to get one and should i just go all out and get it ported and ringed?

 

[hoffscummins]

i would port it and at least o ring it if not fire ring it with some studs imo

you'll have to find someone to weld cast iron for you, and then resurface the exhaust side of the head.

Alabama Cylinder Head. Great price.

Where are you located? You can get new heads for about 550 to 600 shipped. Are you wanting to upgrade the head or leave it stock?

Thats why they invented the three piece manifold.......

Give Garrett a call @ Pure Diesel Power. He'll get you a new head and o-ring and/or port and polish it too Cummins 6B 5.9L 12 Valve Diesel Loaded Cylinder Head Dodge Ram

i would buy a new head due to heat with these engines. you could weld it with a silicon bronze tig rod with a little pre and post heat. i would only do that if you were in a bind but still if you had to pay to have it welded you would still have to pay to have it resurfaced so you would still be looking at least over $300. if you plan on power mods get the work done now instead of doing it twice. don't rush yourself and make a bad decision. let a few other people chime in you might get a better idea.

thanks i am actually putting the engine in a 68 f250 so i want to do every thing right and once. Where would a good place be to get the head and also the port/polish and also fire ringed. And also on the fire rings do you need to get the groves in both the block and head or just the head? Sry i am kind of new to diesel performance.

 

[MColussy]

also i got about 200,000 miles on the engine if i am this far along should i just rebuild the thing too?

 

[a3ftgiant]

o-ring is in the head only, fire ring is in the block and head

 

[Dual K20s]

Not always

The difference is o-rings supplament the headgaskets fire ring and seal to the HG and head which seal to the block.
Fire-rings replace the one in the HG and seal between the head and block.

O-rings are generally regarded as better for a street truck because they last longer. Fire-rings need to be redone every so many miles, but they hold more

Having the head off is nowhere near close to having the block apart. And 200,000 miles isn't much. Check what the cylinder walls look like and decided from there. Mine looked great @160k

Like I said talk to Garrett and he'll hook you up
