Duane beat me to it. Absolutly, no question, use high quality blower pistons. Ford has a pretty stout bottom end, Attention to detail is key when pressurizing your intake. ARP (plug) bolts are a must in rods and mains. Stock rods are good with a little prep work, peening and polishing. All clearances must be checked and double checked. I have customers who tried to save a few dollars on pistons despite any advise, only to have their stuff break, and that sucks...The saying goes, "pay me now or pay me later". Just .02
