Ok I traded my aem uego and 100 cash for this head last nite. this head is suppost to be a z6 gude head. I inspected it as best I could last nite but truthfully I dont know what I was looking for....This kid has a good rep so thats why I went through with the deal. But now idk....I have a z6 head in my room and as you can see they are very different. So my question is is this maybe a y8??? and does it look built??? Here are some of the specs he gave me on the head.....ok here's everything on the head:
It's a Z6 head with
5 angle extreme port & polish
complete race valvetrain
Dual valvesprings
.5 oversized valves
HCP Gude High Lift Camshaft
Guaranteed to give 65-80 HP to the wheels
All performance products and machining done by Gude performance


If more pics are needed or anything,let me know I can take more. thanks

 

that is not a z6 head. Looks like a d15 or a y8.
