Thanks for the Tip Simon and yes, Much much more impressive.
And that is quite an amusing find, lets end this now in the obvious absence of facts there really isn't anything more helpful to say.
PS sweet 32 Mate.
Cheers,

Metallurgical expasion rate can be taken into consideration when developing engine clearances, this means that the overriding key area of interest in the reduction of "slap" will be the tolerances of the engine.
People on GTROC seem to have this almost religious belief in the abilities of a handful of people which is fair considering some of the posters on that website are very very talented people.
However on average I have never heard such a large torrent of absolute crap from a large number of people who really don't know what they are talking about.
Plenty of twincam RB's at 12000RPM+++
Not sure on the lift though although I woulnd't assume so.
Think about it, at higher flow levels the increased area and variability between INLET and EXHAUST with added tuneability becomes an even greater benefit.
Yes valvetrain lighter, single valves cannot geometrically fulfill the same area as multiple valves can.
Do not let people convince you that just because the single cam heads are still faster in the VL's that this means that they are a better option then a twin cam head.
