360 stroker...piston questions.....

Ok, I'm sure this has been asked 100 times before...

I have a 74 Cuda that I will use as a cruiser...very occasional drag racing. Got a 360 block, cast 4" crank,
Mopar I beam rods, not sure on heads yet (maybe Eddys, maybe mildly ported cast) and I'm getting stuck on piston choice.:cry:
EVERYONE says to use forged pistons. I can get some KB356's cheap. I know they will have to be milled
into flat tops for me to use with this setup. But why the avoidance of the KBs? They seem to be quite the high tech piston...and will be HALF the price of forged! :P

Don't worry! I'm building another (MUCH higher HP) for one of the Cudas below!! :king: :P

thanks
