16V 4AGE interferance engine

[merc-blue]

Hey guys.
Im trying to avoid building my 4AGE to become a interferance engine.
Im curious at what stage of cam lift and piston heigh etc at what stage do valves meet pistons in the event of a belt breaking.

My most extreme setup would be 11:1 comp about 8mm lift and 1mm OS valves by that stage the pistons need to be carefuly machined so they dont hit valves with good timing let alone none.

So hoe far can i go. ayone got experience?

If you had the motor apart and got some play doh you could check the clearances and work it out that way.

Im trying to work it out before commiting too buying cams/big valves etc
