We weren't able to get our hands on a new GM valley cover gasket (PN 12558178) in time for our engine assembly, so we were forced to reuse the stock one. Like the oil pan and front/rear cover gaskets, it's a controlled compression aluminum carrier design like we described in our gasket sidebar last issue. After thorough cleaning of all surfaces, the valley cover is set in place and the bolts torqued to 18 lb-ft. Though ARP has bolt kits available for the valley cover (PN 434-8001, $36.04 for stainless hex-head bolts), we had to use our F.A.S.T.-supplied button-head cap screws which, with their flatter heads, give enough clearance for the thicker-than-stock F.A.S.T. intake to sit above.
