compatible parts interchange

Will newer heads and intakes fit a older style (69) block? I want to build a honest 350 horse 350 cu.in motor, and I have both new and old style heads. I do not usually work on gm motors so I need some advice here. I also have 327 pistons and large journal rods (5.7). Any help greatly appreciated

yes the heads & intake will bolt up but you will have to get a fuel pump block off.what will you be putting it in ? the flex plate is different the hole in the center is smaller on the newer motor.
