I'm guessing your from the US as we in Oz never got a Maxima model that used the L24E. But R30 Skylines sold here had the L24E engine, and the head on those engines used a 'closed chamber' version of the E88 head. This head will bolt straight onto an L28 block, BUT the CR will be bumped to around 9.5:1 or even higher depending on the pistons you use. So good for performance, but you'd need to be careful to use premium grade fuel. A small down side of this head is that it uses the 'small' 42mm inlet valve, but this is easily changed to the 44mm L28 type.

Note that all of the above applies only to Oz spec L24E engines/heads. The US got some heads that we never saw, so the end result may be totally different......

Been around L series 6's for a long time and never seen an N47 head in Oz (but doesn't mean they aren't around). The P79 is definately a US model spec head and I think has round ex ports, possibly with inserts (??). I'd say you'd be best asking on one of the American Z sites about this.
