Nobody knows what cams these are????

They look stock. If they are aftermarket they are probably regrinds. Measure the base circle and see if they are smaller than stock.

Based on the second to last picture with the "F" on the cam I would guess stock cams, or possibly regrinds. The "F" is a factory grind designation and have seen "A, B, C, D, and F" cast into many 4G63 cams over the yaers.

Aftermarket cam manufacturers typically do not cast identifiers into their cams, as most use common engine specific blanks to grind a specific profiles to, and then identify them via a custom grind number, like 546/547, 264/272, or XYZABC.

If these cams are an aftermarket set you will need to look more closely for a series of numbers on a flat or machined pad somewhere on the cams.

Thanks bud. Ill check it out and see if i can find anything else.. My bc 272 cams sound nowhere near what this sound like. They have alot bigger of a lope in them. The car does a nice steady idle, has good compression, and timing is all right! So im not sure
