do yourself a favor and take a hike to a hardware store and get 4 1/4x2" allen studs or cheapo bolts you can cut the heads off...that way its no problem, it'll set down nice and even...TQ in 3 steps..
i use those blue rubbers only...never a leak in like 4 times having it off.....just RTV in the corners for like an inch....the felpro gaskets all have notches, so the intake ones will connect right in the head gaskets, you'll see...
don't RTV on top of or under those Blue silicone seals, not supposed to...only do up the corners once you have the gaskets in place....
