As I understand the 3.0L V6 Mitsu engine requirements, a Fel-Pro gasket does not require a re-torque, but otherwise it should be done. It's a real PITA, tho'. Below is what the manual states as procedure for reassembly of cylinder heads on a 1989 Dodge Raider V6 (3.0L Mitsu):

Installation (SOHC)
1)Ensure mating surfaces are clean and dry. Note identification mark on front of head gasket. Identification marks are: "R" for SOHC, "2DN" for DOHC non-turbocharged, and "2DT" for DOHC turbocharged engine. Install head gasket with identification mark toward timing belt side of engine and facing upward. Ensure all holes are aligned.
NOTE: Install head gasket with identification mark toward timing belt side of engine and facing upward. Ensure all holes align. Install washers on head bolts with chamfered side toward bolt head.
2)Install cylinder head and bolts. Ensure washers are installed on head bolts with chamfered side toward bolt head. Using proper sequence, tighten bolts to specification in 2-3 steps. See Fig. 5. See appropriate TORQUE SPECIFICATIONS table at end of article.
3)Apply sealant to rocker cover sealing surfaces before installation. See Fig. 6. Ensure rocker cover gasket projections are aligned with notches in rocker cover. Coat all "O" rings with oil, and install a new "O" ring on distributor adapter and oil dipstick tube.
4)Coat camshaft area with oil prior to installing distributor adapter. To complete installation, reverse removal procedure. Tighten bolts and nuts to specification. See appropriate TORQUE SPECIFICATIONS table. After engine reaches normal operating temperature, allow engine to cool, and retighten cylinder head bolts.
