Hi all.
I'm just putting some new Rhino tappets on to my motor. Its a 1641 thats going in my Type 3. it has standard rockers on it and a Scat c25 cam. They came with 4 spacers per side should i use these or not?
Thanks Telf

If you are going to install these these you will have to check that the rocker geometry is correct, you will find the swivle feet are longer then the factory adjusters, some times you have to grind the under side of the rocker arm so the adjuster can screw in further, the out come of this is that at half the valve lift the adjuster should have the same center line as the valve, some times you have to use a different lenght push rod as well as shimming the rocket post.
