Bought a used FP manifold...

[Shooty]

As the title says, I bought a used fp manifold and to my surprise when I received it, it had some cutting done to it to clear the bolts and washer I suppose. I've linked some pictures

I was wondering if it the cuts were too deep that would cause some cracking over time or else...
The runners seems to be really thick but I would like to have a second opinion before I bolt it on the car

Looks like they were trying to make some reliefs for ARP turbo bolt washers to fit into. Not the greatest solution since the OEM washers fit the manifold just fine.
Based on your photos I don't think the cuts are deep enough to affect the manifold

Iv'e had turbo manifolds come with cuts/reliefs when turbo charging N/A cars. I think its normal for manufacturers of kits to do. It's not the best way to do things, but I think thousands of people run these products without issues. I't looks like there is plenty of meat under the cuts from what I see too.

Thank you for your answers, it had me wondering since I had it in my hands. I'll bolt it to the car and hopes for the best! Thanks again

If you want to give yourself some piece of mind, you could always go in with a die grinder and give yourself some very modest radii where the clearance cuts are located.

For strength, even though you end up with less material:

Not sure if it's worth the trouble though. There are other parts of the manifold that see more stress and would likely fail first. Usually these suckers fail first in the areas where the thin runners start merging into the thick meaty sections.

These cuts should helps prevent cracking, but like you said I don't know if it's worth the time spent on it.
Even though I'm feeling confident as is after all
