I'm a former Fel-Pro engineer... and was the lead Tech Line member and seminar trainer for North America. Your question is the the #1 head gasket question... for all gasket companies.

All blocks/heads will have additional casting holes.... to remove sand during the casting process. The gaskets are designed to control the flow pattern and volume of coolant between the block and head. Typically, the front casting hole(s) are blocked so to allow coolant to move towards the rear opened holes... picking up heat as it flows.

Some engine designs require a FRONT directional stamping (Fords)... for the same purpose. Mopars are smart... no directional stamp required.

The SB Mopar is directional (fool-proof) as it has dowel pins that only allow the head gasket to be installed in one proper direction ... per LH and RH banks.

Install and move forward with the assembly.
