Ive got a brand new ls7 block and iam trying to decide on pistons, the block has been honed from new, I want to know whats the most popular pistons people are using? Is it ok to get 4.125 pistons and used the factory honed bores or is it better to get 4.130 pistons rehone the block for the slightly larger pistons?

liners are already thin on that block. you would want to avoid removing any more meat if possible.
