You will need ls6 valve springs to run the cam as stock valve springs are only good for .500 lift. everything else should be good. id replace the lifters and add some aftermarket pushrods. and since the 5.3 has a smaller bore then an ls1 make sure the valves don't hit the block.

Just use the GM MLS head gaskets. They will be fine and are fairly inexpensive. On the pushrod length, you need to measure to make sure you get the right length. It will change with the heads milled that far and depending on what lifters you decide to go with.
