I haven't looked for a little while, but there are the speed pro hypers at 1.755" compression height & the kb167s at 1.81".
Plenty of options if your just looking for stock replacement pistons, but not much with a taller compression height.
The kb167's are the only ones available that have a taller compression height. Ford on the other hand has 4 pistons for the 289 and 302. Mopars don't have much available for them in the performance industry.
