There is a piston the size you want or close at least its the SRP 1.48" forged dead flat top not a left over 383 23 degree chevy job like the kbs you speak of.
Yup, they're good slugs too, only suit 5.7" rod so A9L's are out.
The only thing to watch is comp if running dead flat top slugs in a 355 with early heads & zero deck - it's usually pretty high, gotta be carefull.

I don't generally hang the slugs out the deck for street engines - little gain & if you need to mill the decks in the future the slugs will have to be machined & everything rebalanced. If you run zero deck you've got a light skim or 2 left in the block before you have to worry about machining anything else.
For comp engines I've run them up to .012" out the deck on a .045" gasket - so .33" piston/head clearance - but that's pushing it a bit.
