on first buildup i had only stock style z28 springs when it spun up good, now i had the tfs heads with higher spring pressure with 1.47 springs to handle my .525 lift. the heads are new and i just got through checking all pushrods and spings also just swapped back to 1.5 rockers to see if its my lifters not handling the new heads. ive never had valve float so i dont know what it sounds like. before it only spun to 7k because i let out of it. thanks for all of your help
