5.3 head on ls1 5.7? PTV?
Seriously though, youll already have the head off. Thats the single reason no one ever wants to check it. You have no reason not to take an hour an make sure. Your playing Russian roulette.....(although it honestly "should" be fine). But how are you going to feel when your hand is on the ignition and your ready to fire it up for the first time? Your going to be praying your PTV is OK.
