Okay lets talk valve chamber/valve spring specs. I've had a 97 autococker and that one had a really short valve spring which I'm assuming was a nelson spring, about 3/4" long. My orracle has the longer springs and works on 1.25" valve springs. I just got a 98 STO which seems to have a lot of preload on the valve spring when I put the valve in. I got a Tornado valve that came with a 1" valve spring and it's fitting just great.
Any idea on the exact specs on the depth of the valve chamber for newer autocockers? I'm trying to come up with a measurement so I can check this STO body and see what spec it is.
