Stock 89 Valve covers on a GT 40 Head

[83 Capri 5.0]

Will they fit with a 1.7 roller rocker?

You'll have to grind out the webbing that holds the small oil baffle in place below the filler neck on the passenger side valve cover. A Dremel too will easily do that. My 1.7 Cranes fit under my stock valve covers on AFR heads with pedestal mount rockers just fine.

You can grind it or do a little hammer work like I did. They'll work though.
