Just remembered I have pictures of my EQ 318A heads that just came back from the machine shop a couple weeks ago. I looked at a set of Speedmaster aluminum heads I have here and the coolant passages are all round, same as LA version Edelbrock heads.
The EQ heads were always designed as a Magnum head to begin with, and it's coolant passages are like triangles, and maybe bigger than Speedmaster and LA heads.
So, if you guys are running Speedmaster or LA version Edelbrock heads, you should be good with any Cometic gasket that does NOT specify that it's for EQ heads. That means j par ordered the right ones for his, i think.
First picture is Speedmaster. Second picture is EQ 318A.
