The way I understand it the .400 offset are for E heads without pushrod tubes welded or deleted.
The .700 offset are for the big time wide ports. The T&D shafts I have say 1.7 on the exh rocker and 1.8 on the intake rocker. Not sure exactly what that means since the numbers are so close.
The offset on the Jessle .903 lifters look to be about as far as you can move them.

The 1.7 & 1.8 usually refer to the rocker arm ratio.

I had not pulled them out of the box in years, in a hurry, made a post and went to work.
I thought the whole set was 1.8. Nice set of rockers with 4 extra.

Yeah Paul.
I made the post and was on my way to work 5 minutes later when I realized my brain fart. Nothing I could do about it, could not delete it, edit it in time.
I know how it looks. In a hurry, people asking me questions, lot on my mind.
Life goes on. Lot bigger thing going on in my life at the moment, good things.
I wanted to answer RA462 quickly because he is cool, try it sometime.
I have 4 sets of roller rockers and 2 sets of shafts and most of them say what they are right on top.
For some reason I was thinking the Jessle lifters had their offset stamped on them thats why I opened up the box. Glad I did, wanted to check them for rust. They are all good, had a NIB set rust on me before.
