Very curious, If I set my timing using the static method which is suppose to be 10 degrees btdc, then check it using a timing light with the vacuum line off, should i be seeing 4 dedrees atdc?

Hmm. Normally the timing would be the same with the retard disconnected. Are you sure you pulled the line to the distributor and not the line to the EGR valve?

yes, I pulled it off right at the distributor. But....thinking about it now, i may of not plugged the line. Would that change things?

Could have, but in the opposite direction. The vacuum leak might make it idle fast, which could advance the timing (through the centrifugal advance); but you saw it retarded instead.
