I got a new wire loom for my centerbolts to take the wires off the covers and put it to the side of them. The brackets utilize the bolt holes that are between the header flange and the valve cover. Only, the kit doesn't include bolts :confused:

Anyone know what size I need to get?

I'm pretty sure I know what you're talking about. They should be 1/4"-20. Get the shortest ones you can, 1/2" or maybe less. Socket head cap screws aka, allen bolts should be easier to work with in that area.
