got new edlerbrock crome covers but they have 10 holes made for older engines ,my 87- 307 has 5 holes ,cant find gaskets with 5 holes they all have 10 holes and when I put them on the three on top leave half a hole open, any ideals how to fill these holes

 

rtv, color of your choice...

 

thanks bigD,

 

got problem solved find some 3/8 metal button plugs pushed in bent tabs on under side, no harm to gaskets and looks good
