Can’t decide which project to head for next

I need rods (out of stock) then my new assembly balanced for my 422 engine so I’m dead in the water there. Waiting for a little warmer weather to pull my powerglide to see why I didn’t have second gear. My son will be needing an engine hopefully this year but I’m not getting excited there till I see him putting forth some effort (short block is done), and money. Ethans Speedmaster heads need finished but his new house is being built so that’s his priority right now. So I’m kicking around jumping on my TrickFlow heads again even though I really don’t need them right now. So how about a what if post. What do you guys think a TrickFlow head would pick up cfm wise on a stock port going from a 2.02 valve to a 2.05 intake valve? We all agree the heads max out in the 300cfm area but I will again do some before and after numbers on the same port. It may take a few days as I have a mess to clean up after back to back intake manifold porting.
