They are button head. From memory, 8mmX1.25, don't remember length. FAST has the installation kit on pdf on their web site, the fastener list is at the bottom.
Stock intake bolts work fine (the ones that hold the intake to the heads, not the valley cover bolts), I never used the supplied intake bolts. You must use button head bolts on the valley cover to prevent damage to the intake.

Rather than buying home improvement center fasteners, you might do better by using the correct fasteners from F.A.S.T. or a supplier like McMASTER-CARR. Quality shouldn't be questionable for automotive use.
Hey Vettenuts, have you pulled the intake back off and looked to see if you have any indents from the stock bolts?
Stock bolts that secure intake to heads, not the valley cover. Valley covers I used the supplied FAST bolts. Sorry for the confusion, I will modify my original post in case someone pulls this in the future.
Just in case Lowes is a bust, you can order the FAST intake bolts and washers separately.
FAST p/n's
Bolt - 54038MC - $1.62 each
Washer - 54038MCW - .32 each
After what happened to Roger (Arkay99) I decided not to use the FAST bolts and re-used my stock intake bolts (the ones that hold the intake to the heads). They fit perfect and I am not sure why FAST replaced them, especially since they rust like crazy and look like crap after a while.
