I want to put a pair of the Ford Racing boss 302 valve covers on but I need to know how thick of a spacer I need to put under the stock upper intake half.
Has anyone used these valve covers and what can I expect??
Stock hood? If you put too tall a spacer on, you may have interference issues. You should be ok with a 1" spacer but I would clay it up first before bolting it on.
Man, my EGR spacer rubs on my stock hood, and I'm using an Edelbrock Performer without a spacer. Although, I do have an aftermarket kmember and aftermarket motor mounts. That may make the difference.
