Jim, It is simply a matter of cost and increased reliability and piece of mind. The supply of the 2.0 journal rods are drying up and the cost is going up for what is left. The hyper pistons are less expensive than the cast replacements. Same with the cheaper forged rods. Cost is about 1/2, plus reliability and strength are improved. In your case I agree with the T/A heads, I would zero deck for quench and do the reverse chamber dish we talked about previously. I'm just trying to help the guys who want a little better than the stock rebuild with the Buick 300 and stock heads. The cheap rods will also benefit the Rover guys too with the 305 pistons.
