I'm having my heads reworked, and I need to know the maximum amount I can have my heads shaved without making the timing chain too loose. I'm guessing that the numbers on the cam sprocket correspond to degrees advanced, right?

.040" or little over. Or you can get cam tower shims

I also just got my head back today & the head was shaved .008 so can i assume that i dont have to shim towers?

MSA shims .015 inch

If you shave your head people will think you are a nazi.
