Per this thread: https://www.civicwagon.com/showthrea...identification they look like 92-93 B17a cams...kinda hard to see under the little lip that holds them into the head since you took the pictures at a bit of an angle.
Don't 94'-01' intake cams have a little concave line around where the distributor slots into?
I have heard that... and the answer would be not all of them do. I am not sure what the year break is, but it may be that '96+ GSR cams have them... or more likely, '00+ GSR cams have them. I have inspected two un-molested B17A engines through the years and the camshafts have the same markings as those of early JDM B16A engines. These engines are so uncommon... keep in mind that less than 4000 were produced here in the US, and it is becoming more uncommon to find an un-molested/virgin B17A engine. It is more common to find these engines parted out, and then who knows what you are getting. The best way that I can describe the engine (as it was described to me by Factory Honda Engineers) is the B17A is a "stroker B16A". Also keep in mind that the advertised HP figures for a B16A and a B17A are similar, so it would be unlikely that the camshaft profiles of the B17A would be more aggressive than those found in a B16A.
I posted the link to the cam identification page a few posts up, according to them it seems to be the B17 cams, unlikely or not. A friend of mine has a B17 engine, although you're right in that it's not stock. They are pretty rare in the wild, but they are out there, and if they've been parted out, those parts have to go somewhere.
DumpdEJ6, the picture with the red writing of the B17A cams at the top of your link are absolutely '94-01 GSR cams and thus, incorrect information... however, the "ff squad" picture farther down in your link with the single groove around the ring "may" in fact have merit. I agree with you that it is sooooo difficult to be sure about identifying the original cams because it is so rare to find one that is un-molested. Once the cams are out, any seller can claim ANYTHING about the parts origin and the unsuspecting buyer is at risk.
here are a few more pics if this helps . . . . just putting it out there when i took apart the block it had P73 pistons, P61 rods, b16 block and cylinder head is PR3-3
From the link I posted, they are "nearly" identical to the picture claiming they are 92-93 B17A cams, minus the small groove on the very top of the exhaust cam. JRCivic1 says that's incorrect, that the picture that claims it has 92-93 B17A in it is wrong. While I respect his input, I am skeptical. I haven't found any more cam identification sites since photobucket went full retard. Unless someone else wants to step in and drop some knowledge, I don't think this will get resolved, we're at a bit of an impasse.
DumpedEJ6, the two photos that you have posted above from the link you have found are BOTH wrong... the lower photo that claims to be a '94+ GSR camshaft is actually a '97 ITR. If you do some research on that one, you will find information that disputes that photo and proves as I have suggested. So, since that photo and information is incorrect, it is not a stretch to think that the cams identified as B17A cams in your top photo are incorrect as well. Since you don't believe me and are placing your faith in the INTERNET... I suggest you find a '94+ GSR, pull the valve cover and cam rails and inspect the camshaft ends. They are common... it shouldn't be too much trouble for you.
For full disclosure, as I have said above, I am not sure exactly what the markings are on the B17A cams... but I can tell you that they ARE NOT what you have pictured.
Now, lets get past this who is right and who is wrong part of the conversation and get to the crux of the OP's issue. WHY do you want to know ??? WHY does it matter ??? Are you writing a book ??? Are you trying to identify them so that you can sell them ??? The truth is that regardless of whether they are B16A, B17A or B18C1 cams... none of them make big power, nor are they aggressive... and thus, are not particularly desirable. They are also not worth much.

I mean, YOU'RE kinda the internet too. No offense intended. Hell, I'm also kinda the internet. I just find it hard to take on faith that you are right and apparently every single cam identified so far on that website is wrong. I do have a friend who just bought a stock GSR engine off of me a few months ago, I just messaged him to see if he'd put the cams back in it yet or not, maybe I can get pictures.
Well I don't know how helpful this is, he sent me a picture of what he thinks is a GSR intake cam. From this link https://www.civicwagon.com/showthrea...identification it says it's a 96+ GSR intake cam, so it looks like you're right, JRCivic. The 94-95 GSR may not have that top concave ring, and the 96+ might.

Asking for vavle adjustment. I was setting valve lash at .006 Intake and .007 Exhaust as per my honda civic helms manual for the b16a2. But it seems that gsr valve lash is .007 Intake and .008 Exhaust. Turns out my camshafts are from the 92-93 GSR which came with the B17 engine.

Reason: valve adjustment

Thank you for helping to get this solved. You were right on this one B17A1 cams from 92-93 gsr.
