I am rebuilding the head on my engine (b18b) and ordered some "OEM b18 valve seals" from kmsmotors. Well I had them overnighted to me for an extra 20$ because I really needed them in a hurry. I got them and tried to put 'em on and they dont seem to be right, so I looked up the part #'s, 1221-pz1-004 and 1220-pz1-004. From what I could find they are for an H22 engine. So I emailed the company and they told me that the valve seals are universal and should also fit on my engine (even though they are for an h22). And they won't give me a refund. So SHOULD these fit my engine? I did some searches and couldn't find much info on it.
any help is appreciated, thanks.
