Any benefits/risks in swapping a y8 cam on a z6?

 

I dont think theres much of a point, theyre basically the same, Swapping the head would be good, I think the Y8 breathes better, swap in a JDM D15 cam, that might fit, and its the most aggressive OEM sohc vtec cam

 

The Z6 head is the Type R of SOHC motors, It flows better for Highend power.
The Y8 head flows better lowend but cant compete with the Z6 highend
