Resolved Can Anyone Identify These Valves?

[VT_4G63]

Does anyone recognize these valves?

I'm in the process of upgrading valve springs on an unknown 1G head that was in a car I bought for parts.

These don't appear to be stock valves, and are in decent condition. I'm trying to figure out where this motor is at.

The intake valves all have I-2400 printed at the top of the valve stems.
The exhaust valves all have E-2431 printed at the top of the valve stems.

The attached pictures of the printed part numbers at the top of the valve stems aren't great, they were hard to photograph.

I tried to google the part numbers and couldn't come up with anything. I compared them to pictures of aftermarket valves on STM, Extreme PSI, RTM, etc. and none of them matched.

Just wondering if they look familiar to anyone on here.

Thanks for your time.

Probably those are EngineTech's valves or some brand that is sharing the parts with them.

You were right, I just went to the Enginetech website and sure enough, the part #’s for their 4G63 intake and exhaust valves match the numbers I have here on my valves.

Here is a link to their 4G63 catalog in case anyone needs it. I wasn’t aware of this company until now:
