Ira, I have an Isky in my 100. If I recall it’s a Z11+4 whatever that means. It’s about a 268 degree pattern and the valve lash is 0.018”.</div>

<div>The most likely Isky grind that you got was the T36. It was advertised as the 3/4 race grind.  The full race was called the Isky T46 and was not recommended for a street car.  If I recall correctly the lash was a bit looser. But, you
 should be fine just using the stock valve lash numbers. <br>
