I've noticed that recent baffle kits have pre-drilled holes above the #3 and #4 cylinders. The holes allow you to easily change the upper spark plugs on those cylinders.

I'd like to retrofit those holes to my baffles as I work through my condition inspection.

Anyway, how big are the holes (diameter) and what is the distance from the center of the hole to the bottom edge of the side baffle?

Thanks,

Kyle,

Holes are of elongated shape, diameter 1/2" and 3/4 tall. Distance to the bottom edge from the center of lower imaginary center is 1 5/8". (top imaginary center is 1 7/8" correspondingly)
