Sorry, I do not mean to hi-jack your thread. I just need a little help understanding the difference between the two (o-ring & fire-ring.) What are the differences in the machining process? Are different gaskets used? What are the capabilities of each one(how much boost?) What exactly is the difference between the 3rd gen head and the others?

Thanks

 

I'm sure someone can explain the difference between the two.

Thanks again

 

im not sure but, i heard you lose compression when you fire ring a new commonrail with the multilayer head gasket. is this true?

 

IIRC, can't you put an MLS on a 2nd gen? I think you have to modify a cooling passage or something but can't it be done?

 

Geeeze, Who told you that?? Sounds like something a mudflap expert would say!!!

If you wanna fire ring a new common rail all you have to do is cutout a couple of coolant passages from an older gasket and remove the inner cylinder ring from the gasket to allow the fire rings to seat down in the grooves you machine in the head.

Fire rings take up all the force and heat from the combustion chamber thus eliminating all the stress on the gasket itself. This is why it's a good idea to do on trucks that wanna run high boost, drive pressure's, ect.... and do it on a regular basis without having to worry about having their truck down if they blow the gasket.

how does it feel knowing that your only running 13s and your not the record holder at bandamere

 

Im sure he feels fine since you wernt the one beating him LOL

 

well allen, i know and he probably knows that fuel for fuel id wear him out. seems here lately you been following my post. get used to following. soon as you get your tranny in thats what you'll be doing.

 

MLS gasket no O-ring Studs only. No reason to O-ring with studs and MLS if you are blowing head gaskets with that better check your tune

 

Anytime cupcake!!

But you have to have a truck that runs first

 

yup! Good stuff
