I agree on both counts. Without knowing EVERYTHING you did it could be a number of things. The Distributor setting is CRITICAL as David said. You can check your adjustments with the right side Valve Cover off. When the car is SUPPOSIDLY lined up at TDC for #1 BOTH Rocker Arms rock (they both have clearance.) I also used an old mechanics trick and had a buddy watch a LONG wooden pencil or similar object move up and down in the Spark Plug hole as I turned the engine over. We would precisely turn the engine over until the pencil reached the top and for a split second remained before moving back down. This allowed for perfect Distributor Alignment as well as being able to check all the valve clearances (which could be an issue for you) and allowed us to double check the timing plate alignment. A better way to ensure exact TDC is to remove the block plug under the intake and drop a VERY LONG drill bit (the book says the size) into the hole as you turn the engine over. The engine will STOP when it reaches TDC for number 1 and this alignment is EXACT.
