Cast vs. Aluminum heads and bang for buck..

Yeah either he's looking to sell stuff or don't know pontiacs,the armasteel crank is a beast,now the block will split at 700 or so but that's a different story. The rods are decent for mild builds but anything that's really getting a beating and I just buy h beams.
To be fair he was talking about an aftermarket stroker crank. when I mentioned just getting some easy horsepower that way. The car is kind of big and heavy and I'd like him to have a little something to get it moving. He's not looking again to set the world on fire he just wants well to be honest not get passed by a Prius...
Maybe just a stout like you're saying stock crank rods some custom Pistons and of course, dare I say it LOL aluminum heads....
FYI .. I'm sure I said it before but I think my Speedmaster heads are complete jewels and I see not one flaw..
Just the guru's gettin in my head that's alll...
