Help with Cam identification please!!
Hey guys, I recently purchased a set of cams under the pretense (from the buyer) that they were H22 Type S Cams. I've since figured out that they're not (after receiving them). Anyway, now my mission is to find out what they really are. I've contacted a few shops and so far nobody has been able to help me identify these cams.
Here are the measurements:

Here are the specs based on the information I found:
Intake
Base Circle : 0.940
Primary : 1.180 - 0.940 = 0.240 x 1.45 = Lift 0.348
Secondary : 1.139 - 0.940 = 0.199 x 1.5 = Lift 0.299
VTEC : 1.252 - 0.940 = 0.312 x 1.55 = Lift 0.484
Exhaust
Base Circle : 0.944
Primary : 1.161 - 0.944 = 0.217 x 1.45 = Lift 0.315
Secondary : 1.134 - 0.944 = 0.190 x 1.5 = Lift 0.285
VTEC : 1.234 - 0.944 = 0.290 x 1.55 = Lift 0.450
I understand with tolerances and wear these numbers may not be an exact match to factory specs. I can't measure the duration with what I have available to me.
If anybody has more helpful information I appreciate it! Here's what I've found so far:
USDM H22A1 (’94-’96) Stock 288°/308° 231°/234° .448"/.415" 11.38/10.54
JDM H22 (’92-’96) Stock 296°/300° 232°/228° .456"/.420" 11.58/10.67
JDM H22A (Type S) Stock 306°/310° 230°/230° .469"/.438" 11.91/11.12
The problem is I don't know what numbers are for what. Honestly this is the first time i've dealth with cams so I may be doing something wrong, or missing a step.
Thanks everyone!
