Actually, it's not a big job to do the swap. When I took it down for a look see at the cams and lifters, I installed the SE tapered pushrods. They shorten enough that they can be pulled with everything else intact... I actually like them quite a lot. The S&S limited travel lifters have .200 travel. The SE tapered pushrods move .095 with one revolution - so setting the pushrod length is very easy. Pulling the rear pushrods and covers would be quick and easy...
And who am I to even think about leaving it alone.... I ground the crap out of both of mine to get all four in there

.
I haven't used the new SE pushrods. That'd be very convenient that basically the full required adjustment from zero lash can be had with one full turn.
Nice to know they'll allow for easier install even with the TP boxes and rockers too. When I lost those nice robust Zippers pushrods during the red bikes reassembly the only thing I could get quickly were the old SE pushrods. I hate 'em. But didn't want to wait. Some time they're coming back out though. Twice over the years I've had one of them bend. Straightened one with a rock on the side of the road once and ran it home too

. But some wintery day they'll get replaced before one of them bends again.
