There is a lot of align honing, overboring, crank turning and block decking that MUST be done for a proper rebuild. Don't waste your time, energy and money on a 305 when you can have a 350 for the same effort.
If the 305 needs rings it is time to change to a 350. Spend $100 or so on a junkyard 350 that needs rebuiding and you will be miles ahead.
That is the bottom line.

Theres head gaskets, exshust gaskets and intake gaskets on a head and they all need to be changed. and don`t forget about the valve seals there 2 per valve.

If you are getting a JY 350, have the shop do a quick check of the block. I believe they can do a sonic check for core shift. Also make sure it is not already overbored. Maybe you can even go to a machine shop and buy one of their core blocks that they have checked and warranty if it cracks in two.

A 350 is a 350 whether it comes from a truck or a car. $100 to $150 is the going price for a rebuildable 350.
You have heads from the 305 you are going to port and polish. No need to change those plans.
Rebuild kits for 350s are actually cheaper than for a 305.
Do the leak down test first and see if the 305 is still good.

Yes, it is necessary to have the engine assembled and the starter in position to do a leak down test.
There are no more parts required to assemble a 350 than are needed for a 305.
The problem you face, which has happened to all of us, is that you want everything to work out right away--even though the bank account is slim to non-existent.

What is this "bank account" you speak of?
