Well I'm just about ready to button this beast up, but I want to make sure that I have the timing marks right on the cams. There are LI and LE, and the manual doesn't really say if you use LI for the intake and use the LE for the exhaust cam timing setting. Can anyone let me know for sure. Thanks.

Re: Timing mark clarification
Left Intake and Left Exhaust - look at the little dots on the cam sprockets in the diagram. All the timing marks have to be as shown at initial chain installation as it takes 17 engine revolutions to get it all aligned again.
That is how i have it, but i was concerned that the intake mark needed to be 90 off the head and the exhaust mark needed to be 90 off the head. Also #1 cylinder is the 3rd piston back on the front side of the motor?
