Anyone install Edlebrock aluminum heads ?

I personally don't like shift kits on a driver. Stock tranny's shift well. With a shift kit you get a lot of hard banging shifts when your driving normal. Drove me nuts. Just my opinion.
All you have to do is adjust your pump pressure to your liking. You can do that 3-4 separate ways. After adjusting your pump pressure in a certain range. From a stop, you can really wind out the gears in an automatic. It will feel like, the car has 2 or 3 times more power. The car will accelerate much faster when needed. If adjusted properly, simply don’t push the accelerator as far down to the floor or let off accelerator a little and it will shift sooner and more smooth. If it’s, adjusted in that sweet spot.
Clutch plates are subject to faster wear if shifts are smooth. I have mine adjusted in a few areas that allows me to have smooth low speed shifts or very high rpm shifts from a stop. The car will shift like a standard if I want. Shifting at very high rpm from a stop. Depends how far I choose and continue to push the accelerator during different circumstances.
I thought that’s what shift kits did. But, wasn’t sure because I never messed with one, until you explained it. Sounds like a waste of money. When you can easily make 2 of 3 adjustments without tearing anything apart and accomplish the same thing for free. Unless, I’m missing something about shift kits ?
