1G Cams / Retainers / Spring Identification

[schafer240]

I recently picked up a 1gb that the previous owner has no idea what's been done to it. I can't seem to figure out what these are, any help is much appreciated

Also the head has aem cam gears and 3g lifters and arp studs

Update to add, measured the lift of the cams. Seems to be a offset like 264/272

Intake is 10mm lift
Exhaust is 9.62mm lift

Bare in mind my calipers could be off a little so consider those numbers ish within reason.

Surprised there hasn't been any input. I'm going to pull the head just as a maintenance item and to see what previous owners have done (or butcher'd)

I'll post better pictures of the components then, hopefully someone can chime in.

You are showing us everything and nothing at the same time. Just about every aftermarket camshaft will have information somewhere on the cam towards the front of the cam. And HKS will be clearly visible.

More and better pictures are needed. Then we would actually have something to go by.

It's clearly a regrind, that's pretty obvious... what regrind that is, is what I'm after. Not sure how you didn't pick up on that...

I didn't look through this thread, but maybe it can be of some help.

And clearly you still said everything and nothing at the same time. Reread what you wrote. One picture of the end of a camshaft with no other pictures to reference does not help those of us who are not mind readers.

I did but thanks for trying to help.

I should add I did find another post about another member having mystery cams and they have the same engravings on the front but the poster never got any information nor did he follow up if he did figure out what they are.

I sent him a pm, but haven't heard anything, I'll update if/when I do.

When I pull the head ill degree the cams and post the results to hopefully help someone in the future.

If it had a giant HKS logo, I wouldn't be asking what it is...

Also if it was the case it wouldn't have hand engraving on the face...

I'm not trying to be a dick but you clearly didn't read and look at what I posted.

As for the cams, if you know those are regrind cams and found no spec engraved marking, then the way to know the exact cam spec would be you check the valve events by using a degree wheel and a dial indicator. According the info you provided above, everything you will hear would be just people's guess.
As for the springs, retainers and spring locators, these too, if there is no marking found, then you have to measure. To me, those look like the stock.

Interesting, from all the info I found springs and retainers are the same between the 1g and 2g heads, is that correct?

Because the stock springs and retainers that came out of my 2g head are completely different.

No, not correct. Springs should be different. The retainers and locators are the same as far as I know. I don't know all DOHC 4g63 valve springs, so I could be wrong but at least there are two, one is with blue paint and one is with yellow paint (But the color paint may have been gone by time). 1G's springs are with blue paint which are the same as JDM GVR4 and EVO 2-7. I think 2G's are with yellow paint which have lower free height by about 1mm than 1g's.

Those are the 1g/2g stock spring/retainer/locator.

Interesting, thanks for that info. My 1996 2g stock springs have red or orange on them, and the retainers looked different to me than whats on this 92, I'll have to dig them out and compare them to the 1g's when I get a chance.

This is the only photo I have of my 96 head when it had all stock springs/retainers for reference. Not the greatest but I'll take a side by side photo and get measurements when I get a chance, probably be early next week.

Perhaps it used to be yellow..

 

[schafer240]

Just wanted to follow up, hopefully it will help someone in the future.

Retainers are steel, confirmed with magnet. Seem to be stock.

I don't have the ability to test the valve springs but I also believe they are stock if the Retainers are.

I will post an update when I degree the cams in
