Ok, I need some help/advice..

I have a stock d16y8 motor, running 11psi on a t04e 57 trim, tuned with Crome. I also have a d16z6 head with a crower stage 2 (street/strip) cam, crower springs, retainers, and a skunk2 adj. cam gear just sitting around unused. I have ARP head studs, and a steel head gasket. I am thinking about taking the cam out of the z6 head, and putting it into the y8. How many degrees will I need to adjust the timing to use this z6 cam in a y8 head?

Also, another question is, would it be worth it? Will I gain horsepower using this high lift NA cam, after a re-tune of course? Does anybody know how much overlap the NA cam has vs. the FI cam at the valve? I do not want exhaust gas backflowing into my cylinders or intake manifold...

Thanks

 

ok i was able to find the information I needed about the timing. From what I understand, I will need to retard the cam gear by 4.5 degrees.

Now the question is, does anybody know how many degrees of overlap an NA stage 2 cam has vs. an FI stage 2 cam, or a stock cam?
