will 86 valve covers fit 94 style mustang

jruppert · 04-24-2003, 11:39 PM

I understand that the 5.0 was unchanged but I dont know about the clearances under the EFI upper intake. I want to get some older valve covers that have the holes in them so I can add some air breathers. Does anyone know if these will fit?

I have a set from an 82 GT on the 89 and they fit but, I'm having to put the old ones back on since there's no provision for the PCV vent tube on the older ones.

The 86 ones should work just fine. I remeber my friend's 95, he took off the valve cover to change the rocker ams. He wanted my old set because I had the inside clearanced. Worked fine on his motor.

As far as clearances are concerned, I think there is more room. I am just hearing that the reason why you cant go those valve covers is because of the holes they put in them for the air breathers. I plan on using both holes for the breathers.
