Again, I never asked if it was or not,, I just keep arguing for the sake of argument and just saying what I've heard,, not asking whether it is or isn't or anything....

And umm, I'm letting the shop put my cam gears on, but not adjust the timing, that's all me pal, I'm thinking 12 degrees advance on both cams. Now if the shop had a dyno...

OOO and I never believe ford or people on this board and have found many mistakes in shop manuals... so that's why I keep on keeping on with my keeping on about what I hear and what it may could possibly might be maybe but probably isn't but better safe than sorry.

I know this is a debatable topic, so I just wanted to throw something out there. I myself have no idea what the zetec engine really is. According to Unorthodox Racing, the zetec is an interference engine. This is stated in their pdf. instructions for installing cam gears.



Technically, the 2.0L Zetec is non-interference.

However, since the intake valve to piston clearance can be as small as 0.004", problems may arise at high RPM due to both wear and valve float. This is no doubt what Unorthodox Racing fears as a liability, and what has caused some engines to be destroyed.

Decking the head would (as in many cases) change the engine from non-interference to possible-interference.

Any engine to be run at high RPM must have valve springs in good condition to prevent valve float.

BTW, the cut-outs in the pistons are called valve reliefs.
