    Where to buy 94 5.7 TBI Intake Manifold studs or studded bolts?

    Hey guys I'm doing the intake manifold gaskets on my pickup and the intake manifold bolts and studs are pretty rough, where can I buy a new set of studs that everything mounts to? All of the intake manifold bolt kits don't include studs which I think I need.

    Slow headgasket failure? Would you bother to fix?

    It would explain the slight coolant leak and if the cooling system gets air in it that would explain the boiling after the engine is shut off, when the cooling system isn’t under pressure it will boil if there is air in the system

    Slow headgasket failure? Would you bother to fix?

    I’m a bit new to this gmt400 platform but are these not symptoms of a intake manifold gasket?

    1994 5.7 factory manifolds or shorty headers?

    Ended up going with Dorman manifolds from Amazon. Install was very smooth, only hang up was the spring and nut for the flange. It seems the spring got mashed to hell at 25 foot pounds.

    Would this exhaust leak cause performance loss?

    I’ve only had this truck for 6 months. 372,000 miles. The cap, wires and plugs were done recently before I got it. It runs really well at idle but If I try to give it the beans shes a let down. I was hoping that fixing the shattered manifold would help with the performance but she’s not a hot...

    1994 5.7 factory manifolds or shorty headers?

    That’s good to know, I’m not looking for gainz but since I need to buy new manifolds anyways I was seeing if it’s worth it to go with headers. At this point I’m leaning towards a set of dorman manifolds

    1994 5.7 factory manifolds or shorty headers?

    How do you guys go about removing the temporary paint and getting proper high temp paint on them? Or do I even need to worry about painting them?

    Would this exhaust leak cause performance loss?

    Manifolds broken and I’m just holding the front port

    Would this exhaust leak cause performance loss?

    Does that mean it wouldn’t make a difference?

    1994 5.7 factory manifolds or shorty headers?

    Discovered a broken manifold today on my 94 5.7 Should I go with factory style manifolds or is there a good set of headers that are carb compliant that you guys would recommend instead? I’m in California

    Would this exhaust leak cause performance loss?

    I have a 1994 Chevy k1500 with the 5.7, I knew I had an exhaust leak but didn’t realize it was this bad. The truck runs good (no check engine light) but the performance is terrible, could this be why?

    What's to know about a 95 model?

    @sync Exhaust gaskets, intake manifold gaskets, and throttle body gaskets should be done but other than that they are solid, my 94 has 370,000

    New Crate L31 Replacement Parts

    I have to agree about the replacement electronic quality. I would rather pull a pocket full of old factory sensors at pick n pull than use a new Ac Delco part.

    I need replacement exhaust manifold bolts for a 1994 5.7

    @someotherguy The Dorman 03412B kit showed up today, should be a direct fit for the passenger side. I ordered the Dorman 675-217 kit for the driver side and it should fit well. Here is a picture comparing my old bolt with the new bolt:
