The BEST exhaust manifold bolts?

[Rocket Man]

Only one way to find out. Probably not until after our August vacation. I can say that I have had three of the bolts out and back in so theres that.

Well that’s 1/4 of them.

Yup, but neither of the back two. You know the ones you cant get a straight shot at through the wheel well. And how about that dip stick issue. I need to get that out too right?

I've never had luck finding an actual part number from ARP for my motor.

Not just to replace bolts. If you’re replacing the manifold then yes. At least on my 4.8 LY2. And as far as listing them for your engine @swathdiver they just list them for LS engines. It’s kind of confusing since they say “Gen III/ LS” but afaik Gen3/Gen 4 use the same exhaust manifold bolts and I’m also pretty sure ARP says LS as in all LS engines.

Thanks, gonna think on it for a bit. The bolt kit is cheap enough to be worthwhile insurance.

Affirmative. All the same.

134-1102 or 134-1202

I went with the 134-1102 6-pt, the 134-1202 are 12-pt heads.

I have two broken bolts. I installed the "brackets" as the solution. The reading I've done on this indicates the OEM replacement bolts installed correctly are a good reliable fix. I think it was mentioned the OEM bolt design is changed for better durability. To get the old broken bolts out will probably take an experienced mechanic with e.g. a welder.
