Am I ok with this? KB107 in La block

I have a 360 La block. (Factory crank and rods , resized and balanced)

I have begun installing my kb107 pistons and I notice the first one number 1 is almost flush with the deck.
The number 2 piston actually sticks up.
(I'm not exactly sure my written numbers on them are accurate with a feeler gauge at home)

Should I do the others to see more, or quit right here, I called the machine shop and they told me ,I can pay more to have it resurfaced again, just depends on how blue printed I want it to be.

Second question is if I am out of the hole , am I am to use my fel pro 1008 head gaskets with the factory J open chamber heads?


Thanks
