with a dish piston heads would have to be less then 64 CCs . just did them same build as what you have used about the same cam was a erson and used the speed pros hyper flat tops with the pbm thunder heads up grade to arp rod bolts .nice mild build .i would say were your weak link is the cast pistons they will not like to much of a beating if you put any power adders the hypers will take abit more .used a set on a 350 with a B&M mega blower with 10 of boost many years ago they held up for the beating and was a stock rod 350
