[Bored&Stroked]

Here is what I do . . . I watch the lifters for a given cylinder. I turn the engine over by hand until I see the exhaust open, right before it closes, the intake will open - I let it come up and then back down. Once I see the intake lifter go all the way down (will be just after BDC), then I turn the crank just under a half turn (now you'll be close to TDC on the compression stroke - valves will be closed). Adjust away . . .
