intake bolts
I pulled my intake to clean and put new gaskets on and I was wondering if I can replace the bolts and hardened washers ? The bolts appear to be grade 5. Where can i find the washers? What are your thoughts?

You should be able to get hardware locally. I suppose you could buy an ARP kit, but you don't need special hardware for the intake manifold. Here's another thread

I replaced mine when I changed out the intake manifold gasket. I can't recall if they were Grade 5 or Grade 8. None-the-less, my local Ace Hardware had the exact fit bolts & washers of the same Grade.
