Regrind Cam?

Thanks for the replies!
The timing is set at 16* initial and has 34* at 3400 and the idle speed is 850. The vacuum advance is connected to manifold vacuum.
The compression ratio is 9.9 and I am using the 1.6 ratio rockers, so the lift is a little more.
With the 904 auto I have to slip into neutral at lights and that gets a little old. Since it's not a daily driver it's not that big of a deal I guess.
I have it apart now to replace the timing chain so it's a good time to change it out, or not.
