A big shot of nos would take care of the low tq number :lol: . Those heads are too big really. The car won;t accelerate, and yank the car on the gear changes. This is a case where good power on the dyno, won;t translate to good et. I have seen it a lot. Shops keep going bigger and bigger, ot get air flow numbers on the flow bench, but the cars don;t run what would be considered correct et's and mph, for what the heads flowed, and, what the engine actualy made on the dyno. Epoxy in the runner, to shrink it up, would be the only way to make those heads work, but, they would work good then. Port them fully, get the airflow numbers up, then fill them in, to get the "velocity" right, with the goal to loose as little flow as possible, and they would rock. This is what I call being creative. I do this from time to time, when someone is willing to pay for the work.
