What would be a good idea to do to my z6 head.
I was thinking of the usual titanium retainers and good valve springs.
I thought about maybe a cam with good lift but shorter duration.
Or maybe changing the engaugement point of v-tech changing to around 4,000 rpms.
Port matching of course.
maybe a little of porting to smooth flow valve ports.

 

V-tech

 

Definatly get a cam, and I'd port and polish the head, you can get alot of power out of the cylinder head, Portflow/Endyn/lasky racing.. or buy a dremel and do it yourself, its not to tough just very time consuming.

 

I dremel and lots of practice on toyota and chevy motors so that I'm not worried about but what which cam spec to look for.
Max lift on v-tec lobe can I get away with.
