Looking for some measurements on 273 commando valve covers.

Thanks all for the measurements AND the extruded heatsink idea is AWESOME if I can find a close match . that might be a good way to go just so I don't have to wait forever for my light weight CNC to mill down the fin"s in about 6 hours per run per fin (X6SUCKS). I have to use this CNC machine right now since funds are not available for me to upgrade my rig to better stuff yet.
The measurements are going onto the valve covers in grease pencil right now to see if they will fit stock valve covers and how they might be massaged to look like I want them to. I don't want a clone of the commando ones Just something the wife can live with and I don't have to say it's a commando clone just a custom wire harness loom holder since I want the spark plug wires separated more for a cleaner look of the wires and valve cover. I'm gonna CNC the plastic pieces to hold the wires so the shape of the holder can be modified to just a taller Slot the plastic fit's over instead of cutting wire guide holes and then making the plastic piece fit over that.

ok about 1.75 or so inches wide =.75 or .8 tall on the wire loom piece, .3 on the short fins and about a .25 or so fin gap. gotta go look at the single length hmmmmmm , a hair over 6.5 . that just might be doable or close with an extrusion hmm. if I get taller and cut down the non wire holding ones and make a tab in the tall one to hold wires. yeah might work and save me a ton of time and CNC stress.

THANKS ALL! I'm looking an extrusion that's close to this.
