The 4 valve heads heads on our 5.4 have no direct comparison to the 4 valve heads that are common in the US. When Ford Oz decided to use the modular here, they apparently sent some engineers over so they could play in the Ford parts goodies bin and the engine development went off in a slightly different direction. we have 2 different valve lifts used in 3 different HP output engines-a low comp 10:1 approx 350HP+368 lbs Ft torque, then a high comp 11.3:1 approx 390HP + 375 lbs ft TQ then another rated at 424HP & 380 lbs ft TQ. (+/- approx only) and they ALL have a forged bottom end.
Me I'm using the 350HP engine and I'm going to go the the Hi-comp pistons down the track. That being said I love things that rev as I spent a lot of time building Rotarys in Mazda's and NSU's as well as multi valve/multi cam engines as well, so that don't phase me at all.
IMO its hard to beat the sound of a high revving V8 and with the right bits the mod motors rev HARD, and will rev hard all day long-not that you need to. The heads on these motors just flow unbelievable numbers in stock form and there is now a good range of cams to suit, with Herrod doing some here that sound so old school its great. If I find that I want more grunt, water injection and a blower will do me just fine.
Yes the engine is one BIG mother and about the same weight as a Big Block, but you can now get an alloy blocks for pretty reasonable $'s-still dearer that a Dart etc but hey....that's the way it is

The point being, and I have said this a thousand times, without a blower, turbo or being sprayed ,they are torqueless wonders, that's not the case with an FE or stroked Windsor, in most cases these 2 engines produce too much torque. The mod motor does rev, which is great on the TRACK, but for the street, if you want those big numbers, where tq is needed, forced induction is a must.
