Swapping cam, should you also...
When you swap out cams from the stock ones, I know you should do the pushrods to an adjustable one, but I was also curious about replacing the tappets? How many of you have done that, or is this something that should just be done anyways?

The Twin Cam lifters are automotive type units, identical to Chevy SB1 lifters (which can be had for $12 apiece), so they are very strong- no need to replace them. You don't have to replace the pushrods either, but most do to save the hassle of removing everything above the stock one piece pushrods in order to get them out.
RE: Swapping cam, should you also...
Do the lifters too, dont know how many miles you have on the bike, but I read an article that said MoCo recomends changing them at 25000 miles. Dont know if that is true but I did with my cam change. I used Fueling but have heard from a couple of builders/tuners they are a little noisy and they preferred SE lifters.

RE: Swapping cam, should you also...
When I installed Head-Quarters HQ-0034 cams (.500 lift), Doug at HQ told me I could use the stock pushrods and, if I was replacing the tappets, to use the HD stock "B" lifters (~$25 ea.)--that's what I did. Service Mgr. at my HD dealer told me the same thing and recommended not using the SE lifters or adjustable push rod kit they sell for $139 (that includes the tubes) because they have had the push rods hitting the covers.

Most people will tell you the stock HD "B" lifter is as good or better than most and alot cheaper. I put a new round of them in when I did mine but I had 38k on them.Stay away from the SE lifter. Have heard several reports of them detonating. If bike has over 15k I would replace them. Not expensive and make a mess if one did let go.Most people do not have any trouble with the SE adjustables but have heard a few that did. I haven't in 15k miles. If time and ease of cam install is not a factor then stock or Perfict Fit if needed is fine.

I looked at the Fueling tappets, seemed like a fair price for a set ($113), haven't read/heard too many people using them though.

The Twin Cam "A" and "B" lifters are identical. And, as I said, you can get the identical lifter from Crane, under a Chevy part number, for less money.

I will look into those crane lifters also, do you have the Part # as well? Otherwise I will try and sift through some of the information myself.
