    Safe max cam lift ?

    Just sent my cam out for a regring and want to know the safe max lift so my valves don't smack my piston? Stage 2 is .416 and the stage 3 is .426.

    Well the correct way is to measure your piston to valve clearance or do a valve drop but if you head hasnt been shaved you will be fine with factory clearances,
    Id me more worried about your valve springs and retainers making sure they work with the amount of lift you plan to run.

    I have torx racing springs and Ti retainers . So I be ok with these? Head is a brand new casting never been cut.

    You need to post a pic of the retainers for me to see. You may meed to change them. Springs are fine. You dont need to worry about cam lift. The lifters do not allow for anything more then .426. You would need to go to manual lifters in order to run higjer lift cam.
