I'm going to be ordering this ford crate engine part # M-6007-x302 this week, http://www.americanmuscle.com/frpp-306ci-crate-engine.html, and i was wondering if any efi intake will work with the m-6049-x306 heads, like the trickflow or edelbrock performer, holley systemax, and will my alternator clear the tall valve covers they supply part #302-070 or would i have to use fox valve covers but will the fox covers fit over the 1.6:1 roller rockers, also with either the valve covers that come with the engine or with fox covers would i have to run a phenolic spacer on the intake to clear them, thanks.
