Engine and Trans Removal

Picked up an engine hoist over the weekend and looking to pull the existing trans and motor next weekend. I'm not quite sure where to go for mounting locations. Heads? Intake Manifold? Exhaust bolt? What's the best and easiest?

I was going to pick up a hoist leveler for the job also thinking that would make life easier.

The existing motor has the carb and manifold installed and was planning on putting the new motor in with both installed as well (ideally). But most pictures I see on the net have the manifold off when using the leveler. I don't care so much about the existing motor but when the new one goes in that I've spent so much time and money building I'd rather there not be chain rubbing or pushing awkwardly on parts.

Is a lift plate and leveler an even better combo? Lastly I don't have springs on my hood hinges. Chances of me getting away without removing the hood? Aligning is a PITA

Thanks in advance
