I emailed the seller to check what model the cams were from, and he said the cams he has are marked 3BF, and he believes they came off a 88-90 model bike. Not sure if they will be OK ? I was looking to swap out the intake and exhaust ones as the ones he has are quite good.

Do you have the cams from thundercat ? Or valve lifter/shims ?

I bought a complete TCat, head (no cams) and a second without the casting (valves springs collects and buckets, there might be shims as well). I have a complete 3tj head with the cams at the end of the week.
The 3BF is the usa model, I dont think it had an exup. Exup allowed the tuning to be more at the top end taking advantage of the variable exhaust.

Sure...if these bits will fit and work for my early 1WG (non-exup) model, then great. PM sent, in case you miss this message. Thanks.
