i just damaged my valve thinking instead of fixing might as well build my head on k20z3 motor
what do you guys think. i live in CA so trying to keep it smog legal except my bolt on. my current set up cai,h,e 60mm,and FP.
these are my ideas
1. port polish the head matching header and im ports
2. s2 cams stage 1, with valve s2 pro vlave springs+retainers and base
3. A. standard compression s2 valves, +.5mm larger
B. high compression s2 valves, standard size

any ideas, what do you guys recommend ?
mainly looking for mid to high power, budget of 2500
then later upgrading my clutch to exedy with type s flywheel
