ive just got the z6 block and y8 head, i figured it would be a better combo.....from many things ive read the z6 bottom end is stronger, better oil pump, etc. and the y8 head is better for my purpose (i dont need the 3hp of flow on the top end).....plus its better at resisting detonation.....i just need more info about the setup, ive been running mine for like 8 months, but i had to ghetto rig a a6 tensioner pully to make the z6 t-belt tight enough.....whatever though lol

I like the y8 heads for the fact that the stock cam is a hair larger, flow better, and have a nice quench area. If you were going with an N/A setup, i would more likely say the y8 is the way to go. It also jumps your C/R up because of the head design over a z6. My friend runs a d15 with a y8 head and pg7 pistons...somewhere around 13:1cr he claims, but man does that thing flow at 7800 rpm.
And from everything i've ever seen and read, supposedly the a6 block is the strongest, although the z6 and a6 block's are pretty much identicle. z6 oil pumps are better though

OLD *** thread but yes, it's the dipstick. The z6 stick is in the front and center, off the block, comes up in the middle of the header. The y8 one comes off the pan, therefore if you put z6 pan on y8 block, you have no dipstick. That's the problem I ran into when I blew my z6 and went to replace it with a y8 bottom end. That ------- motor still doesn't run right to that day. I lost the ------- z6 to a wrist pin C clip. I am still pissed, and it's been over two years.
