I am pretty sure everyone running Edelbrock LA heads and Speedmaster heads are going to be fine with the vast number of LA part numbers Cometic has. I fully believe that note about EQ and Edelbrock heads would only be seen if you are looking up gaskets for a Magnum based engine.
The LA version of the Edelbrock head has more typical LA coolant passages, so that note does not apply to LA engines.
I am running Magnum version Edelbrock heads and EQ heads, so I need the gaskets with the note for them.
The thing they said about EQ moving oil feed holes is flat out wrong. It does not have any oil feed holes.
