Jet change needed?
 

I'm switching from Stainless Marine Exhaust Manifolds to Eickert Headers. I'm running a holley hp 950 carb, but other than the exhaust change nothing else has changed. Do I need to worry about changing the jets in my carb this spring or am I fine to leave it as is?

I doubt an exhaust would cause you need to rejet.

No need to change jetting for that.

If you were already on the edge of lean I would take a look at it. If you are changing plugs keep the old set and after a run or two compare a couple of the old to the new see how much leaner it went. KEs scavenge pretty good if you have a cam with decent overlap.

Thanks for the inputs guys. I figured I was safe but I'd rather ask and make sure.
