hey guys. does anyone have any tips or know what size bolts i need to plug up the emissions lines that run into the back of the heads? i purchased a set of brodix heads and am removing the smog pump and emissions lines. also, what should i put on the bolts tp keep them from coming loose since these are exhaust holes? any help would be great.

Thanks

Go to your Ford Dealer and buy part number F4ZZ-6E086-A. These are the plugs to fill those holes. RAY THE PARTS MGR.:)

9/16" coarse thread bolts worked in my TWs and a buddy's AFRs. I couldn't find any short enough so I had to cut them down.
