If i have a D16Z6 block will my D16Y8 cylinder head bolt right on to it? And if i still use my stock cylinder head will i have to modify my harness at all?

 

I think you would have to use a B7 dizzy for that combination. or your y8 dizzy and modify the harness. If you used your z6 dizzy the cam timing would be off. Also, you would have to mix and match the head bolts becasue one of them will be too long.
