I promise I searched for this answer before posting assuming this is a basic question, but I think it's too basic. So I'll be the first dummy.
I have a '77 440. The block has enlarged coolant ports (figure 8's.., see pic) and the TF 240 heads have offset large holes that line up with one side of the fig. 8 holes in the block.
With all that being said, why do the head gaskets have a small slit opening for coolant when the holes in the head and block are so large?
I searched for head gaskets for '75-'79 blocks, because that's the years I understand the 440's has this configuration, but the gaskets all seemed to have the same small slits as opposed to holes.
What am I missing?
Thank you in advance as always!
