I was just talking to a guy at a machine shop over an engine and it really threw me off.... he said that the heads were made so the engine could be a bit higher in compression.. 10:5:1.. i'm not sure what he meant by that and most likely misunderstood so i am going to ask you guys to help me out...

My questions is... do the heads make the compression or does the block make the compression?


I'm pretty sure it's the pistons make the compression but hey i could be wrong
