What valve covers will work with '87 F.I. 5.0 H.O. with Ford Racing 1.72 roller rockers and the stock cam and Cobra intake? I bought what was supposedly a set of 1.7's off Ebay but when they came in they were 1.72's.

I wanted Ford Racing EFI covers but I don't know if they will work. I see Canton makes a pair CAN-65345 on LRS that are supposed to clear most roller rockers and fit under the stock intake.

Both of those covers will work, but if they're not specified for use with EFI, you'll have small problems.
#1, they won't fit under the stock intake unless you use a spacer. The throttle linkage will contact the passenger side cover.
#2, you'll have to figure out an oil fill system, they have PCV holes ready in both and the driver's side will have the upper intake over it and the passenger side will have the throttle cables over it.
The reason I said that is because many don't realize the difference between EFI covers and carbureted covers. Plus with as many Ford Racing covers there are, I'm not sure which ones you're talking about.

The Canton covers should work, they might need some slight clearancing around the center bolt recess. It'll be right between two rockers and they might slightly touch. The rockers being 1.72 and not 1.7 won't be enough of a difference in terms of valve cover to rocker clearance.

Check out BBK because I had same issue with my 95 and they had several different applications for the 87-93 models.You might have to remover the oil baffle but if so thats real easy.

All I had to do on mine was remove the baffle inside the passenger cover. No grinding or clearancing, just unbolt it. I'm still using the stock valve covers.
Like Eagle said, the real key is make SURE you have the EFI covers. Otherwise, sell them and buy the EFI version. My two cents.
