I'm wondering that too. If anything, the boost will help push the valves open. I'm not going over the stock rev limiter either. Is this some old school V8 myth?

The down side to hydraulic lifters;

Hydraulic lifters have a greater chance of floating at high RPM's and under high power applications ("valve floating"). The chances of floating goes up with wear on the lifters. this means that you have to back off the power a litle bit at high RPM's. Shouldn't be pushing the Zetec past 7K RPMs much anyway, so it shouldn't be a problem.

I'd suggest solid lifters if you're going big power and/or high RPM's.
