Default Z6 head bolts Vs Y8 head bolts

The magazine I am ordering the headbolts have different part numbers and prices. Are they the same damn thing or are they really different. I am using a Z6 head on a Y8 block if that makes a difference.

Well I can't speak to that specific situation, but they are not identicle. I know for sure one will be of the wrong length.

did you use y7 or z6 head bolts? i think you have to get y7 but why if the head is what the bolts are going threw wouldnt you match head with bolts?

So what bolts should I get. I can grind the one down and round the edges to prevent stress cracking
