Default 335 HP 396 290 Head Casting Build & Dyno Test

A while back I was looking for a transmission and came across a complete 335 HP 396 Stocker drive train for sale and and bought it. From what I've been told this engine/trans ran 3-5 tenths under the index in D/SA trim, dyno data also came with the engine which I will share as well. My plan is to go through the 290 head castings and see if I can make some improvements then dyno test the engine and finally run it in the car. I tore the heads down and preliminary cleaned them for a flow test, which I will post as the car ran 3-5 under the index. I will be testing the other head as well before any work starts to make sure it's similar in flow to the first head tested.
