Advaned Auto parts GENIUSES!!

I need valve covers for a small block Chevy.
Ok, what year or gen?
It doesn't matter they are all the same.
No - they are not.

Yeh....heh. and let's not forget the 55-59 Chevs with the top two bolts canted in from the bottoms, which is why most gaskets have 4 holes in the tops
