Is the base circle the same on S&S 570 cams as the SE-259e Harley cams?

My recollection is the bottom of a cam lobe . Cams should all be equal in that area.
I could be wrong and am sure more informed members will correct me.

Some cams need different length pushrods. I'm pulling the SE-259E and installing S&S .570 cams,

What do S&S recommend? Have you checked instructions and other data on their website? Looks to me like they use stock pushrods and valve springs. Tell us a bit more from the outset next time - you still haven't told us what year and model bike you have.

It's a 13 Limited, I'm using the 110 tire shredder kit #92500037A. It comes with SE-259e cams and I think the push rods were OE length.

You answered it for me, I finally found the instructions on the S&S site it says stock push rods will work.
Thanks for all the replies.
