iv been looking like crazy to try to find some sort of I.D. thread on H series cams. Iv looked at euro R cams and they are both smooth on the ring (like b16 cams) that is how my exhaust cam is but the intake cam has some grooves in it so idk If I have a euro r exhaust cam and h22 base intake cam? idk. retainers are def aftermarket but have no markings. if any one has any links or knows anything about what I have I would love to hear it



exhaust cam



intake cam


valves

retainers

 

Measure the vtec cam lobes with a digital micrometer.

 

Hmm, valve pic now too, which are flat-faced. Odd that there are stock cam gears on there with everything else seemingly upgraded...

 

I measured the cams when the motor was apart but my digital calipers are pretty crappy (got them for free can't complain) but if I remember right the intake was about .283 lift and exhaust was .272 I think. which I thought was pretty small but idk.

 

those valves look like DHR valves

 

I really hope not lol everything in the bottom end of this motor is top notch

 

well take a look
