The engine was just rebuilt I was told!!!

You guys are great. I will keep the bottom end as it is for now. The top end has only heads(213s) which kinda suck. I have no carb or exhaust/ headers, but I do have a torker 2 intake, so I will needs to plan those. I don’t even have a radiator. So to get it running, I need to prep the entire top end. No easy way around that but I am glad to hear that the bottom end is workable. Thanks and keep the advice coming.

turn the heads upside down and fill the combustion chambers with water and see if any of the valves leak....

Edit: Install the spark plugs to keep the spark plug hole from leaking during the test...
