New valves

Just ordered a valve kit for my ENGL head, I read online that EL84 ran amps do not need to be biased because of their design and modern valving etc etc.

So in theory I should be able to just pop the new valves in and blow the house down rite?

I'd check the manual for your head. In my mark V manual they explicitly state you don't need to bias the tubes because tubes are tubes and they did it properly the first time and the values don't wander off.
a quick google does yield some results of how to bias some ENGL heads. It might be different for each type though..
