S**^%^%&

It just occurred to me that the new exhaust valves are shorter than the ones that came out of the head. I should have ordered the ones that are 4.98" tall, not the 4.88" tall ones
So I guess I'll have to see if I can get me 6 or the 4.98" ones. Even if there is enough adjustment in the rocker to account for the different length, the springs are going to bind and the angle between the rocker and the tip of the stem isn't going to be ideal. Why didn't it occur to me to measure before I ordered
On the plus side, I think I just found a source for these valves that will ship to Canada

And slightly cheaper on the exhaust valves too.
