Yeah, I missed the explanation on the pistons, which in turn brings out more questions when you look at the specific language.

re: the Hurst badges? Likely repops from PP. I have never seen a 70-72 442 W30 adorned like that - looks cheezy. I looked at the window sticker and it does have documentation for the intake manifold, special order paint, OAI hood and the W Machine option. Too bad the top of the OAI and the original carb are missing.
I wonder if the body is in such rough shape, what's the frame like?

Original Hurst Equipped badges were cast metal (which is what the seller of that car says they are made of); the repos are plastic.
The should really cancel the ad, chuck those pistons, and re-list it.![Roll Eyes (Sarcastic)](https://classicoldsmobile.com/forums/images/smilies/rolleyes.gif)
Really, you buy any 40+ year old car, you have NO idea what lurks in the engine, pistons in the trunk or not. Putting high-comp. pistons in the car makes perfect sense to me, and so does keeping the originals. I bet it'd be easy enough to determine if those pistons are stock pieces or not.
One comment about the story re: the badges and the "H" on the heads, these were attributed as being just that, the story given to him by the guy the current seller bought the car from all those years ago. As I read it, I can almost see the tongue planted firmly in cheek.

Good info on the H badges. What cars were they installed in, and where were they placed?
re: H Heads
I looked them up and found this interesting info (WAC) on H Heads and why they are different

Due to the firing order of Olds V8s, number 3 and 6 spark plugs fire in succession. This caused interference at the intake manifold crossover passage, disturbing the exhaust pulses for these cylinders. So Olds engineers had a small horizontal wall cast between the center exhaust port divider and the #3 or #6 port wall (depending on what side of the engine you face),closing off the passage to the intake manifold. Number 5 & 4 ports still fed heat to the passage for fast warm ups and these heads showed improved horsepower ratings; especially when exhaust headers were used. The second modification was the port shape just below the intake valves. Olds actually decreased the diameter of the opening just below the valve head. This created a venturi effect increasing flow with these heads.
