This is a Speed Pro 4. All you have here are two valve reliefs in a flattop piston. The C-4V and C wedge head piston is a different experience entirely. You have a number of choices when it comes to piston rings, conventional, gapless, file-to-fit, ready to install.
When it comes to any piston ring with an end gap, check the end gap—no exceptions. Cleveland piston ring end gaps should be. On the wider side for high-performance applications. Cast pistons are the most basic type you can stuff into an engine. The Mahle ECOFORM cast piston is designed for modern engine building because it is a lighter piston thanks to fresh casting technology and it is more durable than your average cast piece.
All cast pistons have a certain amount of silicon sand in them for strength and hardness. What you get from a cast piston is stability, with predictable expansion properties and quiet cold operation. Ring end gapping can be performed a couple of different ways. Although every engine builder has their own technique for piston ring installation, the best approach is a ring expander installation tool over rolling rings on.

The two dissimilar metals expand when heated at different rates and in different amounts, the layers of the MLS head gasket allow the aluminum heads to "float" in relation to the iron block, this is not needed when the heads and block are both manufactured from iron. My recommendation is the very common Fel Pro part no. And the OEM deck clearance was "nominally" 0. When I'm ordering pistons I shoot for no more than 0.
Cometic gaskets are very expensive Thank you!! Engine builder kept getting noises on shutdown even though the temp gauge looked normal. Pulled the head making noise and sure enough the gasket was backwards. Glad to hear the "root cause" was identified! It's nice when you can conclusively ID the problem!
