I'm finally getting my motor built. I have used a ported set of mustang heads, Crane rocker arm stud conversion kit (p/n. 36655-16), and Motorsport 1.6 roller rockers with ploylocs. I need a minimum of 3" of inside height in the valve covers. The stock valve covers are not high enough. I will be using an explorer intake with a 1" spacer most likely. What valve covers do you guy reccomend? I was trying to stay with the efi style if possible.
Someone makes spacers to raise the valvecovers. Check TransDapt, Canton or do a search. I used to know, need some for some "Cobra" valvecovers. If I run across the info again, I'll post it.
id use the tall FMS valve covers. usually aftermarket rockers will clear the EFI ones if you remove the baffle. those adapters cost almost as much as the the valve covers i suggetsed. you can find the black "ford racing" ones on ebay for $100.
