Can someone help me identify there TrickFlow heads?

My friend, who also has an 86 GT that currently has a set of TrickFlow heads with a 331 stroker, TrickFlow intake, and many more mods. Anyways, the previous owner gave him a ton of extra performance parts when he bought the car. For example, the car has an 03' Cobra IRS installed in it, and the owner gave him the stock 8.8 SRA with 5-lug conversion axles and it also has the adapter bracket needed for 03/04 Cobra brake calipers. He has no use for them and told me I could have them to install in my car, another plus is I could also install a set of 4.10s and have plenty of room to work since the SRA isn't installed.

Anyways I need help identifying these TF heads. I've looked up every number i've shown in the pictures here, and I can't find any results that that help me identify there. If anyone can help, I would greatly appreciate. Thank you! Also, the box shown, doesn't necessarily mean anything, as they could be the box that the heads that are currently installed in his car now came in and the heads I took pictures of are just placed in that box.

TFS-SBF-1 is the Twisted Wedge/Track Heat head I believe. They are older, as the first Gen Trick Flow heads did not put the Trick Flow name on the ends

If you call up TF and give them the 63244-2B number, they will tell you exactly what they are in terms of a TFS part number, CC, spring specs, etc

Thanks! I actually emailed Trick Flow with all the pictures including all the part numbers, and any numbers I found on the heads. Someone on Foureyedpride told me something similar that they were first gen., probably late 90s, early 2000s due to the lack of TF engraving marks and noted they look like 170s.

I actually found out from the 3rd owner, the car has the Trick Flow 360 HP Twisted Wedge Top End kit. Which has the TF track heat upper/lower intake (which I obviously knew), TF 170cc Twisted Wedge heads, TF valve covers, TF Track Max stage 1 cam, TF 1.6 roller rockers, TF billet steel timing set, TF head gasket/valve cover/intake/exhaust gaskets, etc. and a few other TF parts of the kit. Along with a bunch of other tasteful mods. It really needs a tune though as it doesn't pull as strong as it should.
