i have a 470 setup i would like to use that has flat top pistons and comes to 11.3:1 how much power will that give up vs. a dome setup of about 10 -15 cc to get to 13-14:1 i would like to keep cost down and reuse the pistons i have instead of buying new and rebalancing rotating asb. but if it is a big loss i will go with new pistons
