Ok i have a k24a4 head and i'm going to be using a k20a2 rocker assembly and type-s cams and cam gears.
The bottom end is a k24a4 with 02-04 tsx pistons and rods.

The question i have is will i have any clearance problems with the tsx pistons ,and would it be safe to run 50 degrees vtc?

better to limit the vtc angles on the tune to 45.

But the k20a2 rocker assembly is not a direct drop on the k24a4. You are going to need to trip the rocker arms a little bit. Good luck

Sorry, type.. Trim the rockers. They do not fit as good as they do on the k20a3 head. You need to trim a little bit to allow the rockers to be able to move. It is not very hard , just when you put the rockers in, make sure that all of them can move freely

So you saying i would need to trim material off of the sides of the rocker arms to get them to freely move?

I have k24a4 w/ k20z1 head, running 06+ tsx pistons / rods and running 50vtc all day.

I think the 06+ have bigger valve reliefs though but i'm not sure.
