Comp Roller Rockers

[Larry Hill]

Checked a new set of rockers for the stocker and the lift only changed .002'' at the valve. I checked all rockers in the same position on one head. Lift at the valve could still vary due to stand or valve placement in relation to the fulcrum point, and pushrod length or lobe lift difference.

Larry, did it change + or -?

Any variation on all the possibilities you mentioned, will affect the reading.

For your application, my preference would have been T&D P/N 8200 or Harlan Sharp P/N S70015K.

Checked .481'' +/- .001

I assume the 0.481" is for the exhaust lift; what does it check at the intake?
The spec sheet calls for 0.467"/0.483", so at 0.481", +/- 0.001 is quite close.

I try to get all lifts to be -.001'' to a max of -.004. Everyone else in the class has over .500'' lift so I don't want to give up anything.

Agree, smart way to do it.
