Trick Flow small block heads

Any more updates. I'm about to pull the trigger on these to replace my hand ported Eddie's..would be going on my stroker combo..along with a new solid roller.
408
12.3:1 (with TF heads)
Solid roller camshaft (still trying to decide on one, looking at the Lunati 40200734)
Frank Lupo Dynamic 9" 4300stall
4:30 gear
28" tire
150.shot nitrous.
What kind of track times are you getting now with the Eddies? What kind of gains are you expecting?..
