I have no experience with O-ringed heads. But for factory HP I don't think they are necessary. But some guys really like them and say you will never have to worry about blowing a head gasket again. Make sure your liner height is correct first and foremost. If its never been apart I'm sure you will need to cut the counter bores. Cat head gasket and ARP head bolts or i think IPD is offering some special treated headbolts now too.
I'm running 700ish hp on my 6nz with IPD one piece kit. Haven't had any trouble and I'm hard on that engine
