I've got a guy here with a later model flat top b18b valve cover and he only wants $20 for it.

Will it fit on my 91 b18a1 with the ribbed valve cover??

pretty sure it will since I think they all use the same valve cover gasket set but I'm not sure.

I tried search but it keeps saying "search failed" and I sorta need this answer pretty quick...

 

the one with the pcv valve on top right?, i think all you need to do to make it fit is plug the pcv valve hole on the valve cover
