I have a set of wire looms I like on my 68 327. They are flat aluminum and the width steps down. There are 2 piece black plastic strips to hold the wires, that also step down. I don't remember the name. I did find an ad for them in the current "Rod & Custom". The ad refers to to them as "Real Parts", the advertiser is Streamline Hot Rod Parts. They use the bottom screws on the valve covers, and with straight boots hold the wires well above the exhaust manufolds.

I don't own a vehicle that isn't old enough to drink.
