(ford racing valve covers) http://www.gefracing.com/Merchant2/...Product_Code=M6582L302&Category_Code=50ENGINE was just going to have some stock fox ones powder coated, but i really like these. im just wanting to know how tall of a spacer would i need to run them? think a 1" would clear it or can i get away with a shorter one? im pretty sure my hood can clear. i hope.
