Distributor vacuum advance hitting intake.......

Open up a factory service manual, and do it like the factory does it. Or like Old Man Ray mentioned. TDC, timing mark lined up, dist gear lined up with no.1. Takes all the guess work out of it. Never understood why anyone would do it any different.
Exactly. It most certainly "does matter" or else the factory service manual would say it didn't. That's the whole purpose of this thread. The OP found out "it matters".
