Which Trick Flow Heads with 318 (future 408)(part 1 of my plan)

Before I do anything I need to go through what I have now and get a solid baseline. The car is new to me and I'm learning a lot about small block mopars. This is a hobby for me. I'm not a mechanic, but I am mechanically inclined. I spent years playing/fixing and doing some drag racing with 2.2/2.5 turbo mopars.

I need to go over the 318 I have now check leakdown, compression, timing, carb settings and dial it in, but I'm also planning for the future. Winter is coming so the car will be sleeping until the spring so there won't be any major updates any time soon.
