Hi, I started rebuild my '86 1.6 CVH engine, and change lean burn head to the older '84 hemi head. Now I can't choose the right pistons for my engine

Some catalogues have the same pistons for the pre '86 and post '86 engines, at MAHLE catalogue I found three types of piston for 1.6 CVH. Can anybody help me? Whitch pistons I need to use?
