Do leak down test.

if all is good...
then i would mod the engine in this order... bag for buck

1) take of head, clean it, get nice 5 angle valve job, no porting, reface valves, mill the head to bump up CR, new valve seals

2) pick a nice cam & upgrade snap fit valve springs with stock retainers

3) port match stock z6 IM with 60mm b series tb
4) get IM heat insulator gasket
5) degree cam
6) save money for dyno time
