I want to buy a shiny new valve cover for my 250 chevy inline 6 but I cant find a valve cover that has 11 bolt holes . Can anyone help? 377127 is my block casting number if memory serves me right. thanks guys
Also there is a 79 stamped under the GM stamping.

If it's the very late 250 with the integral head, 2bbl version (80-83? IIRC) then there is no chrome readily available for it.

I think you might be right . I didn't think so at first because it didn't have those 2 boxes on top of valve cover and the carb was removable. But I guess it is...
