I will spraying like a 250 direct port shot on this. my question here is while this block is in the machine shop do i want to o-ring the block? i have read that plenty of people are runinng up to 800rwhp without them and have heard a couple mentions that o-rings can damage the pistons and/or block. i will be driving this often and if i o-ring don't i have to go copper head gaskets? i have heard these are not good for daily driving. help me out guys what do i do?
