Trick Flow small block heads

I’ve whittled down my vans weight to about 3050 with 5 gallons of fuel (iron heads) but haven’t weighed it yet with the TF’s, likely hovering right around 3000 I reckon. Unfortunately I can’t seem to whittle down the gut!
It’s like walking a tightrope when putting a combo together. But the heavier the vehicle the thinner that tightrope gets.
