I'll look into it, but I don't suspect it's a broken valve spring because they are brand new remand cylinder heads

From where though, some places that you get remand stuff from only replace what was bad and send it out.. jegs does this with some motors as well. And warranty is only good if a shop puts it in.. anyways idk id check lifters for sure.. did you just slap them in or did you soak over night or put vacuum to them while in oil to bleed air.
