Hi Brad!

Thanks for the detailed response and sharing your data points.

It looks to me like you saw some shift in the valve lift curve with the B3 kit as well. What I was pretty astonished by is the valve lift INCREASE early on on the EXH side, see below:



In this case the 'zig-zag' curve (so up early on and then down past the mid-lift) was only present on the EXH side and the B3 kit's only impact on this was to again drop the lift, so no net contribution. I could not explain why I saw this, I did measure several times thinking that maybe I literally missed my 0 (zero) starting point, but no, everything matched.

I emailed Mike @B3 my details a couple of days ago, along with the lift charts, hoping to hear back from him in the next few days.

Given my intended use, which is street, I am looking to do my pushrod length measurement this weekend and get me some pushrods ordered. Have a few sets here, but I suspect the lengths are going to be off by some measure given the extra height of the B3 kit.
