305 head gasket number?

Can I just use the universal 262-400 small block head gasket or is there a 305 head gasket made for the 305? I cant find it on Summit? They have a set, but its the whole gasket package which I dont need. I just need the head gaskets.

A general application 350 type will suffice.

A 350 head gasket will work on a 305 bore? Won't that cause some weird spots in the chamber? I know its not much, but it'd be some...

Using a 305 block and 350 heads, should I go with a 305 or 350 gasket?

If your using a 350 head you have to use a 350 head gasket, or the gasket will cover some of the chamber.
