My 85 C-10 has a 1962 small journal 327 block and 1970 400 heads, long tube headers, dual exhaust in with flowmasters exiting in front of the rear wheels.  I recently blew a head gasket and sent out the heads to get a complete valve job and machining done.  What head gaskets set should I order for this set up?  Will a standard 350 set work?
Secondly, I'm planning to replace my stock intake with the Edelbrock 7104.  Any opinions on this intake?  I plan to use my stock Qjet carb.  Any hood clearance issues?
