Best replacement pistons for stock '69 engine

Hey guys. So, this being my first engine building venture outside of VW/Porsche world, I'm overwhelmed with piston choices (in that, there are more than two choices).

I've got a stock, original 1969 318 2bbl out of my '69 Barracuda. It was very worn out and was bored 40 over at the machine shop as part of the rebuild. Now I'm looking at pistons. I'd like to stay as close to the stock CR as possible, maybe slightly higher is fine (better than slightly lower). My old pistons have 4 small valve reliefs on them, but that's all I know. Most replacements I see seem to be flat top, and I'm not sure if that's compatible. The rods are stock and floating pin.

I'll be replacing the cam with a stock grind, for what it's worth. So, just a daily driver engine with a little more pep courtesy a 4 barrel intake and carb, plus TTI exhaust.

These look like they would fit the bill, but are they of reputable quality? $155 seems awful cheap for 8 pistons to me, but VW/Porsche pistons are my only basis of comparison.
