Tomei 256/8.5 Cams -bolt Ins?

[yogi000]

Hey everyone,

i've finally decided to install the cams which i've had sitting on the shelf for the past year.

Do i need to check/change the shims when i do the change over??

Also any other pointers i should knowabout? i'll be using the workshop manual for torque setting and the clamp down sequence

I've changed cams on other cars but never a nissan...so any heads up would awesome.

Thanks

George

Unsure how correct it is but I have been told that when changing cams you need to bleed the lifters down as when isntalling new cams it can cause them to hold the valve open a little which in turn can cause a valve to kiss the piston when torqueing them down.

Another option I've been told is that you spin the motor 10-15degree's off TDC so the there's no chance of that happeneing.

I really am not sure as I haven't done it myself so its worth looking in to a little.
