Piston Choice

Hey there people. I had a question about some KB190 pistons. I am planning on installing a set in my 360 .040, I was interested to know if there needs to be any machine work done to the pistons or the heads for them to work properly? Being a quench style and all.

Or would it be easier to use a set of kb107's and replace my 596 heads with RHS's later on? I would think the kb107's would be a good overall choice if I plan on swapping to a closed chamber head later.

There are also a few new cams I am looking into like:
Lunati 60403
Comp PP280H
PP284H

the car:
73 dart
360
904 3000 stall
8 3/4 - 3.73 - 3.91 gears (haven't decided yet)
596 are just cleaned up a bit and worked the bowls a little in my garage, eliminated the exhaust bump. No flow numbers.
Crosswind intake
750 edelbrock which will eventually get replaced with a new holley.


Give me your thoughts. Thanks.
