Got some cams, they don't look right... Options

[Muggs]

I bought some 5sfe cams from another member, advertised as 294's, so naturally I assumed they were webcams. (looking back, he never actually said who made them) They look funny. The lobes have been ground down so far they are almost even with the bearing surface (does toyota even make shims thick enough for these?) the bearing surfaces are uneven and worn. One cam was hard-welded, the other was just ground down. The lobe profiles don't even look that different from stock cams, except that they are now much smaller overall. Have a look at the pics and tell me what you guys think.

hard-welded


not hard-welded


worn


compared to stock


Are these things even usable???

Thanks, Presure.
I checked for markings, the cam that has clearly been hardwelded was in fact marked "web cam 294", the other was unmarked.
Are there shims thick enough to allow these to be used in a 93+ head?

to be honest, im not really sure if they will work in the 93+ head or not. i doubt toyota makes that large a shim.
