I just got a ls/vtec to replace my c1
the head is supposedly shaved .020
When we turn it to TDC the points on the cam gears do not line up together
Is the cam timing supposed to be retarded or advanced when the head is shaved?
Thanks

The cam timing will be retarded by approximately 1 degree.

OK in idiot terms how do I judge that on the OEM cam gears? How many teeth? The way it sits now with the timing belt still on it, it looks as if the intake cam is advanced and the exhaust cam is retarded. The lower timing belt cover is lined up with the red mark on the crank pulley. The upper cover and back are gone so I am assuming the marks would/are supposed to be parallel to the floor?? It came off of a running car, so should I just leave it that way?
What about getting the crank pulley off? Will it hurt the engine if the crank pulley moves clockwise just a little bit? not even an inch?

If you aren't running adjustable cam sprockets, you should just time it according to stock specs (in other words, do not try to move the belt over a tooth). One degree of cam timing is not all that much, so you should still be able to line everything up relatively closely.

The easiest way to remove the crank pulley is with a powerful impact gun, but I'd be careful about turning the crank if the timing belt is not around the cam sprockets.

It is around the cam sprockets. We are trying to change it (the timing belt). We are using a crank pulley tool and a 4 foot pipe on the breaker bar.
So put it back to stock specs and it will not hurt anything? Was I right about the red mark and the sprocket's lines being parallel to the floor?

I wish I had an impact that worked well
75 gallon compressor and a POS impact.....nope

Just follow this procedure, and you should be fine:
