Well, in 96 they changed to a single port header. 97 was the first year the were interference. So if it has dual exhaust ports, it's a clearance engine.
If it has single port exhaust, pull off the valvecover. In 97 they changed from hydraulic adjusters to solid adjusters. So if it has solid adjusters it's interference.

90 - 96 are non-interference.
90 - 96 also have HLAs. this means there is no valve adjustment.
pull a valve cover and look.
