bolts sizes

hey I have vortec heads and I need some bolts to go in the holes right above the temp gauge sending unit and the fan switch the small holes above where these sending units and switches go. I bought some wire looms and they bolt in those holes I think. http://www.summitracing.com/parts/trd-9370/overview/ and does anyone have instructions on how to fold these things thx!

Re: bolts sizes

Vortec heads have center bolt valve covers, those looms in the link are for the old perimeter valve covers.

Re: bolts sizes

once again if someone would help what is the size of the bolt holes on the side of each head, just below the valve cover lip. over the top of the fan switch, and the temp sender?
