my car had over heated a couple times and i think i may have stuck the rings a compression check showed 35psi which i know is about a 100psi of bare minimum compression could it be the valves and if this is a posibilty is there any chance the rings are fine what confussing me is it holds 35psi so would that point more towards the rings because there is no loss in compression? thanks for reading this

More than likely the head is warped. Aluminum heads on iron blocks don't take kindly to overheating. Depending on how bad the engine overheated the rings may still be good. A somewhat decent test is to squirt some oil in the cylinder and try the compression test again. If the compression comes up significantly then the rings are to blame. You could also have burned valves or cracked head due to overheating.Sounds like this is probably going to get expensive.

I'll be the first to admit that I'm not a mechanic. But I always wondered why they put aluminum together with cast iron on an engine since the expansion and contraction rates are different.

Several reasons. Biggest is weight savings. Second is it allows higher compression due to faster heat transfer. Bet you would also be surprised to know that there is no gasket material as you know it in the head gasket. It's 3 sheets of metal with the top and bottom layer stamped with ribs around the openings and a little bit of silicone around those openings.
