So after watching this video and going out to my truck and taking a measurement I found that I am around 0.039 to 0.038 in the hole. Now the standard ideal quench on a sbc 350 is 0.040 so there is no way for me to ideally hit that now.

I just want some confirmation on perhaps if I am doing something wrong or if this seems out of whack or if something seems wrong?

Has this engine been rebuilt ?

Yes, you'll have approx. .054" quench with an .015" gasket.
Not the best - but could be worse , if your dynamic compression is too high this may require alittle more octane.

You can use thicker gaskets, combined with milling the block to achieve desired quench.
More importantly, are all cyljnders equal?
Low buck, machine shop rebuild often use rods that are hastily resized. I found a set that varied across .012" range. You may also find it cost effective to replace vs resize, but that will require rebalancing the rotating assembly.
