valves are good as is the sodium ones will take more s**t than the normal z22se ones the inlets are directly cooled by fuel so pretty tough as isI'm looking at what direction to go with the valves and springs etc, just how much will the stock sodium filled valves handle? I was looking at the supertec dual springs but was unsure if I need to go for ferrea valves or keep the stock ones?
Also do I need to remove the guides to do the porting correctly? and if I do should I fit gm replacements or are there upgrades?
I was reading a thread on the cobalt forum and they were saying they like to do it on boosted applications, I'm not fussed about it been on back as I would like to fit a catch canLooks good but what for?
Wouldnt it be better moving it onto the front like a z22 aswell?
