Without adding in a spacer is there a way to fit tall valve covers under an Explorer intake? I know I can take out one fitting and put a pipe plug in it but on the back of the intake there is a vac tube that sticks down, can it be removed and plugged and will the tall valve covers clear then? I don't want to remove it and find out it still won't fit, I'm hoping someone else has already tried and can give me some advice, Thanks.
