It's simple. Even a novice can do it in a short afternoon. All you need is a set of rocker box and cover gaskets and a cam cover gasket.
I highly recommend replacing the oil pump drive gear with a bronze one while you're in there. Harley should've done it. They did it with everything but the Sporty.
Hammer sells them too as well as a tool to lock it in place while breaking the nut loose and torqueing it back down. You don't want that torque transferring to the flywheel. Really simple.

$450ish total. Cams, drive gear, and tool, cam cover gasket. Best bang for your buck you'll ever do.

Under $450 bucks seems amazing. Oh one more question; will the Vance and Hines tuner be able to tune for these cams? Or do I need a custom tune from someone.

The added lift is done partially by using smaller base circles on the cams and the hydraulic lifters compensate enough for the very small difference to not need longer pushrods. Adjustable are only another places to leak oil and not the route I'd go if longer ones WERE needed. You won't even pull them. Leave them in the tubes. Heads need to come off for the tubes unless you cut the old ones first. No need for this.
No benefit from replacing lifters either tho I did replace mine with S&S premiums but only because they're quieter and my heads were off anyway. I did a 1250 kit too. Still used stock pushrods.


Can't speak for the V&H tuner. I'm carbed.

Easier to see the intake pushrod go up and then back down to know you're on TDC compression and not TDC exhaust. No need to remove heads.
