Default FAST intake bolt sizes?

I'm going to buy the bolts seperately so I don't have to pay double for the stupid hardware kit (bought a used 90mm intake). I really just need the valley cover bolts and the TB bolts as I'm going to an LS2 TB. I'm going to do the 10 manifold bolts as well - figure I should just upgrade to stainless. Here's what I have for sizes:

M8 x 30mm button head cap screws for the valley cover (10)
M6 x 35mm TB bolts (4)
M6 x 110mm intake bolts (10)
M6 flat washers (10)

I can get all of these for about $20 which beats what the kit costs.
TIA

You definitely don't want to reuse your valley cover bolts. The FAST sits lower than the stock intake and will touch the head of your stock bolts. When you torque down your FAST intake you can press it into those bolt heads enough to crack your new intake. If you buy the FAST new it will come with different valley cover bolts that are button head cap screws where the head is about 1/2 as high as the stockers to keep them from touching. As for the other bolts I think you can reuse the stockers.

I was in the same boat as you. (used fast 90/90)

I just took stock bolts and the intake with me to the local nut and bolt supply.

TB bolts were cheese, just make sure you get nylock nuts so they dont come off, I got a saucer shaped allen head bolt for the valley cover

I got the long bolts that hold the intake to the heads with my intake so if you dont have those, I dont know what to tell you.
