Fox Anyone know what heads these are

I could have sworn my old twisted wedges were numbered just like that.
You can call them, if it's their numbering, they will tell you about them if that's what they are.

edit: I looked for some pics that I took when I called them, but couldn't find them.
Regardless, i'm still thinking they are an older set.

I have an old set of TFS TW 170 heads that look just like that. Hand stamped serial numbers and all. No other markings to indicate brand or size.

Here is how my old set of TW170's are stamped and look. These are early 2000 heads IIRC.

Yes, those are the older Twisted Wedge heads, had a set just like.

I think the stamping is just a Serial Number.

Is the stamping the same on both heads, with a -1 on one and a -2 on the other?

Yes sir. I was out of town so still have to pull off the valve covers to check them out. I’ll keep everyone updated.

I wouldn't even bother pulling the covers yet,
Call trick flow with that number first.
