*NOTE: When replacing any cam in any car it is to be expected that you will need to measure and replace shims as necessary.*
The cams base diameter is significantly smaller than the stock cam so any lash shims that you had originally are off considerably.
Throw in cam housing gasket thickness difference. Cam housing depth. And valve job stem height.
You are going to be doing a valve adjustment period.
Few things I can tell you about these cams: base circle is smaller so rather than use very thick shims just eliminate gaskets between cam box and head and use a sealant like yamabond or similar ( NOT rtv). You’ll end up with shims approx. like stock thickness ( you will need to measure all valves). Also, be sure to raise compression over stock or you WILL be down on torque. Lastly, these WILL work with factory fuel injection as long as you slightly bump ignition timing and make some adjustments to the airflow meter.
