Allecotec valves

[misterY]

My valves of the new engine got lost while I was shipping them, so I need new ones. I saw allecotec have a set (AllEcotec Stainless Steel Intake & Exhaust Valves 2.2L & 2.0L Ecotec) with order-no. AE-0010 for 200$. Do they fit the Z22SE (i think they do)? Do I gain some performance using them (better air flow, reducing stress for the valvetrain because of the reduced weight)?

Thanks!

you need standard size valves, unless the head has been machined, the allecotec valves are fine - have a set in mine (but +1mm)

much better flow too

Vocky helps out as always, thanks! But I do not know if I understand you correctly. I cannot use them for my head? Why is it so? They say on their website "They are OEM replacement so no modification will be required. Simply swap them out with your stock OEM valves are your good to go."

Please note, I do not mean the "GM Racing Stainelss Steel Intake & Inconel Exhaust Valve Set .5mm Oversize 2.2L & 2.0L Ecotec "

Yes, the standard sized AllEcotec valves are fine for your standard head.

yeah that ^

what I meant was if your head has been machined for bigger valves buy the +1mmr valves, if your head still has standard size valves buy the standard size wasted stem valves

I just wasn't sure whether the head had been ported/tweaked or not dunno..
