Are these made for square or round coils ?

The coil connection is a round rubber boot that goes over the ceramic protrusion of the coil and the electrode wire goes inside the coil. The coil boot is not square but round! Which was the case with my 2004 GMC Sierra.

Will these fit a 2002 Chevy Avalanche 5.3?

They should fit your 02 Chevy 5.3. I installed them on my 05 Chevy 5,3 and they fit perfectly.

Will these fit a 2006 gmc sierra 1500

i got a chevy with a 6.0 2004 and they fit great so i would say yes they are almost the same

Will these fit 2016 silverado 5.3l

They will fit .the wires are a little longer than the ac delco ones. On the passenger side the furthest away might have to make an adjustment to the heat shield. Check my pictures of my engine.
