Tighe 104 is same as a Wade 104.

I found the 104's valve lift was less than stated. It was only around .318" with stock 1098 rockers. So I put 1.5s on it.
Cam wasn't brand new, had done 10,000km but still looked new.
Graham's 266SS has less advertised duration, but much more @ .050" lift. I'm sure he'll put some numbers up, soonish.
